[Buildroot] [PATCH 2/2] package/syslog-ng: work around gcc bug 101915

[Giulio Benetti]

With Microblaze Gcc version 12.1.0 the build fails due to gcc bug
101915: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=101915. The bug
show up when building syslog-ng with optimization but not when building
with -O0. To work around this, if BR2_TOOLCHAIN_HAS_GCC_BUG_101915=y,
we force using -O0.

Fixes:
