svn commit: r266587 - head/share/mk

[Warner Losh]

New Revision: 266587
URL: http://svnweb.freebsd.org/changeset/base/266587

Log:
  Allow CC to not actually exist. During the ports INDEX run, all the
  Makefiles are evaluated without building things. In a normal build,
  the prerequisites would be built, and CC would be an actual thing. In
  an INDEX build, though, they don't exists. Redirect stderr to get rid
  of annoying messages, and assume that the compiler version is 0 if the
  actual compiler can't tell us. Do this in preference to guessing based
  on numbers because gcc410 might be 4.10, or 4.1.0 and without
  carefully crafted special knowledge we differentiate between them
  easily (also ming-gcc has no clues at all). Elsewhere, don't trust
  the compiler version if it is 0.
