[src/trunk]: src/tools/gcc - Generate a list of *.o -> lib*.{a, so} mapping. ...

[uebayasi <uebayasi%NetBSD.org@localhost>]

details:   https://anonhg.NetBSD.org/src/rev/705e174b6ed4
branches:  trunk
changeset: 749444:705e174b6ed4

description:
- Generate a list of *.o -> lib*.{a,so} mapping.  This is also known by
  parsing dependency lines in libgcc.mk.

- Generate a list of *.o -> *.{c,S} mapping.  *.S files are known as
  ${LIB1ASMFUNCS}.  Assume other *.o files are built from *.c.  This information
  is needed to generated wrapper sources later.
