Revert "main/gcc6: delete in favor of Alpine's gcc6"
This reverts commit d56a2facfb
and changes the main/gcc6 pkgrel to 9999, so it will always be higher
than Alpine's version.

When cross compiling a target gcc, target flags may be used on the host
Configure identifies a number of warning flags (WARN_CFLAGS and
WARN_CXXFLAGS) from the $CC value. The cross compiler may be different
from the host compiler and may not support the same set of flags. This
leads to problems such as:
cc1plus: error: unrecognized command line option "-Wno-narrowing"
cc1plus: error: unrecognized command line option "-Wno-overlength-strings"
Work around this problem by removing the warning flags from the
BUILD_CXXFLAGS value, in a way similar to the BUILD_CFLAGS.
