I'm using both --with-build-sysroot and --with-sysroot when I compile GCC, so
that I can compile it against a different version of the local system than the
one I'm compiling on.  Most of the build works fine, with the exception of the
libraries libgomp, libmudflap, and libssp.

Each of those fails because they do not take notice of the --with-build-sysroot
directive, and thus they cannot find important files like crti.o etc.

I configured with this:

--with-build-sysroot=/tmp/invalid/gcc/i686-redhat71-linux-gnu
--with-sysroot=/invalid

where /tmp/invalid/gcc/i686-redhat71-linux-gnu is an extracted sysroot from Red
Hat 7.1 (surprise!)  Everything chugs along OK until the above-mentioned
libraries, then:

/usr/src/gcc/obj/gcc/./gcc/xgcc -B/usr/src/gcc/obj/gcc/./gcc/
-B/tmp/invalid/gcc/i686-generic-linux-gnu/bin/
-B/tmp/invalid/gcc/i686-generic-linux-gnu/lib/ -isystem

/tmp/invalid/gcc/bin/i686-generic-linux-gnu-ld: crti.o: No such file: No such
file or directory
collect2: ld returned 1 exit status
make[4]: *** [libssp.la] Error 1

make[3]: *** [all] Error 2
make[3]: Leaving directory `/usr/src/gcc/obj/gcc/i686-generic-linux-gnu/libssp'
make[2]: *** [all-target-libssp] Error 2

The other two libraries gave essentially identical errors.  I don't think the
-B etc. options here are correct; they seem to be remnants from previous
versions of GCC, before the --with-sysroot and --with-build-sysroot flags were
supported.

The configure.in files for these libraries need to be updated.
