Subject: Updated to newest ld from pk.
X-Git-Tag: FreeBSD-release/1.1~1117
X-Git-Url: https://git.subgeniuskitty.com/unix-history/.git/commitdiff_plain/7fc7155d6702b18fd4e899147921812b520e80f3

Updated to newest ld from pk.

lib.c:
Pull in archives containing definitions needed by shared objects.
warnings.c:
Less spurious "undefined symbol" msgs for shared library defined
symbols.
ld.c:
Do a better job of recognising data in text segments, eg. `const char []'.
shlib.c,ld/rtld/{Makefile rtld.c}
Use strsep() in stead of strtok() and restore colons in eg. env. vars.
