[klibc] Don't hardcode paths in klcc

[Martin Michlmayr]

Stop makeklcc.pl from hardcoding paths of cc, ld and strip in the klcc
script it generates.  Using hardcoded paths is generally a bad idea.
First, the whole idea of $PATH is that you don't need to hardcode
paths.  Second, klcc is a Perl script but my hardcoding the paths
you make it less portable.
