-std=* for bsd.dep.mk

[Iain Hibbert <plunky%ogmig.net@localhost>]

Hi

I found an issue when compiling NetBSD sources with pcc .. with a modified
pcc in any case. It is this.. if the compiler in use does not have GNU C
compatibility enabled by default, and requires a switch (eg -std=gnu99
which the build framework normally supplies), then when mkdep is run it
does use the C preprocessor internally but -std=gnu99 is not passed..
causing there to be issues because of the lack of eg __GNUC__ definitions
which that would bring in. The source that the depend files are based on,
is thus not quite the source that would have been compiled.

so, I would like to fix that by adding flags matching -std=* to the mkdep
commandline, for C and C++ sources

any objections to that?
