btrfs-progs: build: detect whether -std=gnu90 is supported
GCC releases prior to 4.5.0 don't support -std=gnu90 so btrfs-progs won't build at all on older distros. We can detect whether the compiler supports -std=gnu90 and fall back to -std=gnu89 if it doesn't. AX_CHECK_COMPILE_FLAG is the right way to do this, but it depends on autoconf 2.64. AX_GCC_VERSION has been deprecated, so we'll use that only for earlier autoconf versions so we can drop it when we drop support for older autoconf releases.
