curl-compilers.m4: improve detection of GCC's -fvisibility= flag
Some builds of GCC produce output on both stdout and stderr when --help --verbose is used. The 2>&1 redirection caused them to be arbitrarily interleaved with each other because of stream buffering. Consequently, grep failed to match the fvisibility= string in the mixed output, even though the string was present in GCC's standard output. This led to silently disabling symbol hiding in some builds of curl.
