Use WARNS?= instead of WARNS=
For this to work properly for all part is the subdirectories
the WARNS assignments in Makefile.inc0 are moved to the correspondning
Makefile.inc.
Approved by: obrien (binutils maintainer)
Tested by: make universe
libraries in LDADD so that `make checkdpadd' doesn't report non-errors.
Fixed some style bugs (the usual ones for DPADD and LDADD, and misformatting
of $FreeBSD$).
This finishes up the binutils import. But I am leaving it disabled
in "src/gnu/usr.bin/Makefile" for now. It is not used by anything
yet, so I'll take this opportunity to run one more round of tests
before enabling it.
