Subject: [PATCH] Unconditonally define alloca as __builtin_alloca

This enables alternative compilers, which may not define __GNUC__,
to implement alloca, which is still fairly widely used.

This is similar to how stdarg.h already works in musl; compilers must
implement __builtin_va_arg, there is no fallback definition.
