Added Files:
	pkgsrc/mk/buildlink3: buffer

Log Message:
Change the way in which arguments are processed by the wrappers.  We
know read the arguments by first placing them in a buffer and taking
the argument in the first non-empty buffer as the argument to process.
The buffer is there to allow "splitting" an argument into multiple
arguments (currently up to five arguments), e.g. "-Wl,-R/path1:/path2"
is split into "-Wl,-R/path1" and "-Wl,-R/path2".  Each split argument
is placed into a buffer.  Using a buffer lets us read and process all
of the arguments in a single pass despite "pushing" more arguments
onto the front of the argument array.
