option enable-target-optspace overwrites CFLAGS_FOR_TARGET

[Oliver Metz]

Hello.

I'm building a mips cross toolchain. The target libs (libgcc, libstdc++)
should be optimized for the target. But when using
"--enable-target-optspace" configure switch my CFLAGS_FOR_TARGETS are
overwritten as config/mt-ospace gets included. A similar question was asked
here [1] years ago. There is also a ten years old bug report [2].

Is this the desired behavior of --enable-target-optspace or do you consider
this as a bug?

I tried to configure with "--with-arch=4kc --with-float=soft" but this
doesn't influence the CFLAGS for gcc build.

Regards
Oliver

p.s. At crosgcc-ml nobody was able to help me. [3]
