Who may be responsible for this alignment?
The same Makefile has been used in other distros, and the same 4.7 that I'm using was built on another previous system without problems, but now produces this error itself on the new system.
I bet this is something about the env on the new system, but I don't know what piece is responsible for this alignment.
Any clue?

Hi,
I'm the maintainer of the XStreamOS/illumos distro, mainly x86 but we also have a sparc version.
I'm currently trying to upgrade a T4 system running XStreamOS/sparc as of illumos 2019.
This system contains a gcc 4.7 that I used to build all the various userland components, built on a previous XStreamOS basic system through a gcc 3.
I don't know what changed in the env of the T4 system, with respect to the previous where I built gcc 4.7.
On this system I cannot build any of gcc 5,6,7,8,9,10.
The build always breaks here:

Any chance the linker script is missing an align directive ahead of this section? Or it is insufficient? Or (unlikely) broken?

As an example, the ".libs/compatibility.o" file is built like this:
libtool: compile: /data/sources/sonicle/xstream-userland-gate/components/gcc-6/build/sparcv7/./gcc/xgcc -shared-libgcc -B/data/sources/sonicle/xstream-userland-gate/components/gcc-6/build/sparcv7/./gcc -nostdinc++ -L/data/sources/sonicle/xstream-userland-gate/components/gcc-6/build/sparcv7/sparc-sun-solaris2.11/libstdc++-v3/src -L/data/sources/sonicle/xstream-userland-gate/components/gcc-6/build/sparcv7/sparc-sun-solaris2.11/libstdc++-v3/src/.libs -L/data/sources/sonicle/xstream-userland-gate/components/gcc-6/build/sparcv7/sparc-sun-solaris2.11/libstdc++-v3/libsupc++/.libs -B/usr/gcc/6/sparc-sun-solaris2.11/bin/ -B/usr/gcc/6/sparc-sun-solaris2.11/lib/ -isystem /usr/gcc/6/sparc-sun-solaris2.11/include -isystem /usr/gcc/6/sparc-sun-solaris2.11/sys-include -I/data/sources/sonicle/xstream-userland-gate/components/gcc-6/build/sparcv7/sparc-sun-solaris2.11/libstdc++-v3/include/sparc-sun-solaris2.11 -I/data/sources/sonicle/xstream-userland-gate/components/gcc-6/build/sparcv7/sparc-sun-solaris2.11/libstdc++-v3/include -I/data/sources/sonicle/xstream-userland-gate/components/gcc-6/gcc-6.5.0/libstdc++-v3/libsupc++ -std=gnu++98 -fPIC -DPIC -fno-implicit-templates -Wall -Wextra -Wwrite-strings -Wcast-qual -Wabi -fdiagnostics-show-location=once -ffunction-sections -fdata-sections -frandom-seed=compatibility.lo -g -O2 -c /data/sources/sonicle/xstream-userland-gate/components/gcc-6/gcc-6.5.0/libstdc++-v3/src/c++98/compatibility.cc -fPIC -DPIC -D_GLIBCXX_SHARED -o .libs/compatibility.o
I cannot find what is causing this non-aligned problem.
This is how configure is invoked:
/data/sources/sonicle/xstream-userland-gate/components/gcc-6/gcc-6.5.0/configure --prefix=/usr/gcc/6 --mandir=/usr/gcc/6/share/man --bindir=/usr/gcc/6/bin --libdir=/usr/gcc/6/lib --sbindir=/usr/gcc/6/sbin --infodir=/usr/share/info --sysconfdir=/etc --without-gnu-as --with-as=/usr/bin/as --build=sparc-sun-solaris2.11 --sbindir=/usr/gcc/6/bin --libdir=/usr/gcc/6/lib --libexecdir=/usr/gcc/6/lib --host sparc-sun-solaris2.11 --build sparc-sun-solaris2.11 --target sparc-sun-solaris2.11 --with-pkgversion="XStreamOS 6.5.0-XS-2" --with-bugurl="https://bugs.xstreamos.org" --enable-plugins --enable-objc-gc --enable-initfini-array --enable-languages=c,c++,fortran,lto,objc --without-gnu-ld --with-ld=/usr/bin/ld --with-build-time-tools=/usr/gnu/sparc-sun-solaris2.11/bin --disable-libitm --without-gnu-as --with-as=/usr/bin/as LDFLAGS="-R/usr/gcc/6/lib"
As you can see, I use both illumos as and ld, but I also tried using gnu as with the same result.
I also tried using gnu ld (which is not recommended on a sparc build, AFAIK), but that brought in different problems earlier.
Anyone can help?
Thanks!
