Define following in mk/platform/${OPSYS}.mk;
_OPSYS_PKGSRC_GCC_SUPPORTED
  list of supported pkgsrc gcc versionon the platform.
_OPSYS_PKGSRC_GCC_INCOMPATIBLE
  list of unsupported pkgsrc gcc version on the platform.		
_OPSYS_PKGSRC_GCC_DEFAULT
  pkgsrc gcc version used by default

for example
_OPSYS_PKGSRC_GCC_SUPPORTED=	46 47 49 50
_OPSYS_PKGSRC_GCC_INCOMPATIBLE= 34 48
_OPSYS_PKGSRC_GCC_DEFAULT=	47

Change pkgsrc gcc version selection logic to following:
with GCC_REQD=4.3 2.8.0, and builtin gcc is 4.1,
_OPSYS_PKGSRC_GCC_DEFAULT 4.7 is sufficient and used.
with GCC_REQD=4.9, higher than _OPSYS_PKGSRC_GCC_DEFAULT,
highest supported 50 will be used.
