Building fxload on Microblaze with gcc < 8.x and optimization enabled
fails with:
Error: operation combines symbols in different segments
This is due to gcc bug 63261
(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63261).
To work around this, the fxload package has a !BR2_microblaze
dependency. However, gcc bug 63261 only triggers when optimization is
enabled, so a better work around is to pass -O0, which is what we do
in other Buildroot packages to work around this bug.
So, this commit passes -O0 when BR2_TOOLCHAIN_HAS_GCC_BUG_63261, and
re-enables fxload on Microblaze.
