            Bug ID: 61651
           Summary: Cross compiler will use host as eroneously
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: driver
          Assignee: unassigned at gcc dot gnu.org
          Reporter: martin at netbsd dot org

With a gcc configured like this:

> mipsel--netbsd-gcc -v
Using built-in specs.
COLLECT_GCC=mipsel--netbsd-gcc
COLLECT_LTO_WRAPPER=/usr/pkg/libexec/gcc/mipsel--netbsd/4.9.0/lto-wrapper
Target: mipsel--netbsd
Configured with: ../gcc-4.9.0/configure --disable-nls --disable-libquadmath
--disable-libquadmath-support --disable-libssp --disable-libgomp
--disable-libstdc++-v3 --disable-libatomic --enable-languages='c c++'
--enable-shared --enable-long-long --with-local-prefix=/usr/pkg
--enable-threads=posix --with-boot-ldflags= --target=mipsel--netbsd
--with-gmp=/usr/pkg --with-mpc=/usr/pkg --with-mpfr=/usr/pkg --prefix=/usr/pkg
--build=x86_64--netbsd --host=x86_64--netbsd --infodir=/usr/pkg/info
--mandir=/usr/pkg/man
Thread model: posix
gcc version 4.9.0 (GCC) 

and binutils pre-installed in the PATH, picked up by configure correctly:

checking dynamic linker characteristics... NetBSD ld.elf_so
checking how to hardcode library paths into programs... immediate
checking what assembler to use... /usr/pkg/bin/mipsel--netbsd-as
checking whether we are using gold... no
checking what linker to use... /usr/pkg/bin/mipsel--netbsd-ld
checking what nm to use... /usr/pkg/bin/mipsel--netbsd-nm
checking for mipsel--netbsd-objdump... /usr/pkg/bin/mipsel--netbsd-objdump
checking what objdump to use... /usr/pkg/bin/mipsel--netbsd-objdump

I still get compiler that tries to invoke plain "as":

> mipsel--netbsd-gcc --print-prog-name=as
as

and also tries to use this, which obviously fails:

 > mipsel--netbsd-gcc -v -c test.c

[Bug driver/61651] Cross compiler will use host as eroneously

--- Comment #1 from Martin Husemann <martin at netbsd dot org> ---
Passing AS_FOR_TARGET (and friends) in the configure environment does not help,
but explicitly adding --with-as=.. does fix the issue.

So this looks like a pure configure bug.
