    compiler.mk, gcc.mk: Implement DRAGONFLY_CCVER

    DragonFly has two compilers in base, GCC 4.4.7 and GCC 4.7.2.
    The way one switches between them for userland programs is to set
    CCVER in the environment.

    However, to set this via make.conf is tricky.  I've been using the
    low level "ALL_ENV+= CCVER=gcc47", but this trick fails to properly
    identify the compiler which results in _GCC_VERSION being incorrectly
    defined.

    Additionally, there are some prominent packages that do not build on
    gcc 4.7 and the fix is either not fully understood or would require a
    large amount of work to implement.  In these cases, it is desireable
    to specify the package be built on gcc 4.4 regardless of CCVER setting.

    To address these issues, a new directive is added: DRAGONFLY_CCVER.
    It is only effective if OPSYS equals "DragonFly", and it will properly
    set CCVER and properly define _GCC_VERSION.  It will also allow a
    per package specification of a particular compiler in the pkg makefile.
