[Buildroot] [git commit] package/belle-sip: fix build failure due to gcc bug 99410

commit: https://git.buildroot.net/buildroot/commit/?id=bf89616368ce8eb3212aea5212145e9e4ed8c0cd
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

The belle-sip package exhibits gcc bug 99410 when built for the Nios2
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_99410=y.

Fixes:
