[tlbuild] trial builds for TL'13

[Ettore Aldrovandi]

OK, it builds, now, both i386 x86_64. I used gcc version 4.6.3.

Remarks:

* It needed the patch Apostolos posted. (Solaris 11, however, did not.)

* In freetype2/freetype-2.4.11, configure assumes grep is ggrep
  causing a failure in gmake being detected. ( ggrep is found, but not
  used.) It happens on both Solaris 10 and 11.
