Subject: [PATCH] sbc_primitives: Fix build on non-x86.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Don't call __builtin_cpu_init unless targeting i386 or x86_64.
Otherwise we get an error at link time:
CC sbc/sbc_primitives.lo
sbc/sbc_primitives.c: In function ‘sbc_init_primitives_x86’:
sbc/sbc_primitives.c:596:2: warning: implicit declaration of function ‘__builtin_cpu_init’; did you mean ‘__builtin_irint’? [-Wimplicit-function-declaration]
