Subject: build: check for gcc version independent of platform
X-Git-Tag: v4.1~2256^2~2

build: check for gcc version independent of platform

Use the gcc specific __GNUC__ and __GNUC__ minor to determine gcc version
rather than using the GNU libc specific __GNUC_PREREQ.

This fixes the following compile error with musl libc:
src/descrambler/capmt.c:79:18: error: missing binary operator before token "("
 #if __GNUC_PREREQ(4, 3)
                  ^
