build: fix potential factor build failure on arm and mips
* src/longlong.h: Sync with the latest longlong.h from libgmp to: - Use __builtin_c[lt]zl on arm64. - Fix sparc64 vis3 build failure due to missing __clz_tab. - Avoid a clang build issue on mips. - Support thumb2 arm 32 bit system. * src/cfg.mk (sc_ensure_comma_after_id_est): Exclude longlong.h to ease merges.
