If anyone has any objections, please let me know. ------------------ From: Hisam Mehboob [ Upstream commit d7b2769f8dba3e5f40d2a8a11988812d51160b17 ] Building the rseq selftests against musl libc fails because musl's does not provide the glibc-specific __GNUC_PREREQ macro: error: missing binary operator before token '(' Replace __GNUC_PREREQ(11, 1) with an equivalent check using __GNUC__ and __GNUC_MINOR__ directly. This pattern is portable across all C library implementations and is already used elsewhere in the tools/ tree (e.g., tools/include/linux/string.h). This also allows removing the #include , which was only needed for __GNUC_PREREQ.
