    curl-compilers.m4: accept -Og and -Ofast GCC flags
    
    -Og, introduced in GCC 4.8, optimizes for debugging experience.
    -Ofast, introduced in GCC 4.7, builds on -O3 and enables further
    optimizations breaking strict standards compliance.
    When specified in CFLAGS, these were always overridden by -O0 or -O2.
    Fix this by adding them to flags_opt_all.
