package/lmbench: fix build failure due to gcc bug 101915

Browse Source 
The lmbench package exhibits gcc bug 101915 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_101915=y.

Fixes:
