package/python-brotli: fix build failure due to gcc bug 68485

Browse Source 
The python-brotli package exhibits gcc bug 68485 when built for the
Microblaze architecture with optimization enabled, which causes a build
failure.

As done for other packages in Buildroot work around this gcc bug by
setting optimization to -O0 if BR2_TOOLCHAIN_HAS_GCC_BUG_68485=y.

Fixes:
