Patch Set 3: Code-Review-1

https://gerrit.osmocom.org/#/c/2100/3/Transceiver52M/x86/convert.c
File Transceiver52M/x86/convert.c:

Line 197:       if (__builtin_cpu_supports("sse4.1")) {
It is only supported by GCC, so building with another
compiler, for example with clang, fails:

convert.c:197:6: error: use of unknown builtin
'__builtin_cpu_supports' [-Wimplicit-function-declaration]
        if (__builtin_cpu_supports("sse4.1")) {
            ^
1 error generated.

I don't know, is there any way to determine supported
instructions sets in clang, but for now we can go this
way:

#if (defined(__GNUC__) && !defined(__clang__))
    if (__builtin_cpu_supports("sse4.1"))
        // ...
#endif
