I put in a "head -1" step per your suggestion. However, this will still
leave us with really ugly version strings, along the line of

PostgreSQL 7.2rc1 on hppa-hp-hpux10.20, compiled by GCC gcc (GCC) 3.1 20020115 (Red Hat Linux Rawhide 3.1-0.18)

May I suggest that gcc is being a little too verbose here? Perhaps
"gcc --version --verbose" could do that, and plain "gcc --version"
could try to have some respect for compatibility with prior behavior.
