Rich Felker 64f05291ff ldso: fix missing errno code when reporting relro mprotect failure this code path potentially runs prior to stage 3, with thread-local storgae and thus errno unavailable. for this reason, commit `63c67053a3` removed the call to the mprotect function and replaced it with a __syscall operation that bypasses errno. however, this left the error message printing (which is only reachable in stage 3 and thus can safely access errno) with no error code for the %m format specifier to use. introduce a new set_errno function pointer that points to a no-op until stage 3. this is analogous to the error function pointer introduced in commit `d16d7b1099`.	3 months ago

Rich Felker 64f05291ff ldso: fix missing errno code when reporting relro mprotect failure

this code path potentially runs prior to stage 3, with thread-local
storgae and thus errno unavailable. for this reason, commit
63c67053a3 removed the call to the
mprotect function and replaced it with a __syscall operation that
bypasses errno.

however, this left the error message printing (which is only reachable
in stage 3 and thus can safely access errno) with no error code for
the %m format specifier to use.

introduce a new set_errno function pointer that points to a no-op
until stage 3. this is analogous to the error function pointer
introduced in commit d16d7b1099.
