NetBSD/share/mk/bsd.lib.mk
jonathan 5e0e8cec39 More table-driven changes for different toolchains: 
* new bsd.own.mk variable OBJECT_FMT with values "a.out" or "ELF".
  * use OBJECT_FMT in Makefile tests that depend on toolchain.
  * Add new bsd.own.mk variable NOSHLIB that, if set indicates a given
    port doesnt yet do shared libraries. Set on powerpc.
  * Document new feature-test variables in src/share/mk/bsd.README.
Tested on i386, mips, fakedup Alpha environment.
