meson: don't use compiler.has_header
Meson's compiler.has_header is completely useless, it only checks that a header exists, not whether it's usable. This creates problems if a header contains a conditional #error declaration, like so: > #if __x86_64__ > # error "Doesn't work with x86_64!" > #endif Compiler.has_header will return true in this case, even when compiling for x86_64. This is useless. Instead, we'll do a compile check so that any #error declarations will be treated as errors, and compilation will work. Fixes compilation on x32 architecture.
