[gpsd-dev] patches from pkgsrc: SConstruct

[Greg Troxel]

scons appears to nuke the environment, which I realize has pluses and
minuses.   pkgsrc uses wrappers for compilers, to limit visibility of
dependencies to those that are declared, and to munge linker flags
sometimes.   Those need the pointer to the control file.

And same issue for using ccache.  I would think that people on other
systems would have trouble with ccache not finding the cache dir.  There
seems to be a tradition of accomodating many build systems; I can change
the style to match and push myself if this would be acceptable.

Tell scons to pass the wrapper config variable to children, so the
wrapped compiler works.

Not yet addressed upstream.
