New Revision: 286791
URL: https://svnweb.freebsd.org/changeset/base/286791
Log:
Introduce a new make variable: NMFLAGS.
As the name indicates, these are flags to pass to nm(1). The newer
binutils have a plugin mechanism so, to build something with LLVM's
LTO, we need to pass flags to nm(1). This commit also extends
lorder(1) to pass NMFLAGS to nm(1).
