New Revision: 215137
URL: http://svn.freebsd.org/changeset/base/215137
Log:
Revert r103230, which depended on ld preserving the __start_xxx and
__stop_xxx symbols for custom sections, even when these were not
referenced (at link time). This behaviour was changed again in binutils
commit 0b8ed435c3fe8bd09a08c23920e65bfb03251221.
This time, put the __GLOBL macro definition in cdefs.h, so it can be
reused in a few other places where it will be needed.
