[Bug c++/29780] New: temporary file breaks cross-build

["danny dot backx at scarlet dot be" <gcc-bugzilla at gcc dot gnu dot org>]

Hi,

When performing a cross-build (see the triplets I entered above), a file named
"as" gets created which gets used instead of the right assembler, thus breaking
the build.

Pls. note that I've entered the target triplets we're building (see
http://cegcc.sourceforge.net), this gcc build bug is probably unrelated to
them.

I've had to work around this by using a script such as the one pasted below.

I've reported this to the mailing list months ago (see
http://gcc.gnu.org/ml/gcc/2006-07/msg00533.html ) but someone asked me a couple
of days ago whether I created a bugzilla report, and I don't think I did.

So I'm making up for that now.

Here's the script I use as workaround :
mkdir -p $BUILD_DIR/gpp || exit 1
cd $BUILD_DIR/gpp || exit 1
#
export CFLAGS=""
#
$TOP_SRCDIR/src/gcc/configure \
        --prefix=$PREFIX \
        --enable-languages=c,c++ \
        --disable-interwork \
        --disable-nls \
        --enable-checking \
        --disable-multilib \
        --build=$MY_HOST_ARCH --target=$TGT_ARCH || exit 1
#
# Deliberately no error handling here.
#
make
#
# Because we need to delete this file
#
rm $BUILD_DIR/gpp/gcc/as || exit 1
#
# Now the build should continue smoothly
#
make || exit 1
exit 0
