Also, change sources.redhat.com to sourceware.org.
This patch was automatically generated by running the following shell
script, which uses GNU sed, and which avoids modifying files imported
from upstream:
sed -ri '
s,(http|ftp)(://(.*\.)?(gnu|fsf|sourceware)\.org($|[^.]|\.[^a-z])),https\2,g
s,(http|ftp)(://(.*\.)?)sources\.redhat\.com($|[^.]|\.[^a-z]),https\2sourceware.org\4,g

and then by running 'make dist-prepare' to regenerate files built
from the altered files, and then executing the following to cleanup:
chmod a+x sysdeps/unix/sysv/linux/riscv/configure
# Omit irrelevant whitespace and comment-only changes,
# perhaps from a slightly-different Autoconf version.
git checkout -f \
sysdeps/csky/configure \

Update.
Wed Aug 14 21:36:16 1996 Ulrich Drepper <drepper@cygnus.com>

* elf/dl-lookup.c (_dl_lookup_symbol): Remove fifth parameter
RELOC_ADDR and make NOPLT a set of flags. All callers
changed. Delete condition that checks for resolving to the
location being filled in. Add condition to skip the

* elf/rtld.c (RESOLVE): Likewise.
* sysdeps/m68k/dl-machine.h (elf_machine_rela): Pass
DL_LOOKUP_NOEXEC as second argument to the RESOLVE macro if
processing a copy reloc, DL_LOOKUP_NOPLT for a jump slot
reloc, zero otherwise.
