To get some sense on how is GCC 5 standing, we (myself and Jakub Jelinek)
have performed a test mass rebuild of rawhide (January 15th package list)
using gcc-5.0.0-0.5.fc22 on x86_64, and for those packages that failed also
rebuilt the same package with gcc-4.9.2-5.fc22.x86_64 to quickly remove from
the list packages that fail for non-GCC related reasons.
Looks like there are some new issues with gcc > 5.0.0-0.5.fc22 - my package
got through your rebuild (or was not mention in list), but I see failures
now in Koji or VM with gcc-5.0.0-0.10.fc22.x86_64 (koji) and
gcc-5.0.0-0.9.fc22.x86_64 (virtual machine).
Can somebody have a look at this issue (yes, this is update, but it fails
even with last git revision on fedorahosted which worked well with
gcc-4.9.2-5.fc22.x86_64 [1])? I wonder if there will be more people with
such problems.
Error message [2]:
/usr/bin/ld: ../libssh.a(sshkey.o): relocation R_X86_64_PC32 against
undefined symbol `stderr@@GLIBC_2.2.5' can not be used when making a shared
object; recompile with -fPIC
Indeed, it looks like openssh passed with 5.0.0-0.5.fc22;
unfortunately I don't have the logs of the passed packages anymore.
I'd firstly take a look into diff between config.log with 4.9 and 5;
it sounds like some -fpic detection configure routine failed. Maybe
it passed the rebuild only by luck (?).

The only difference in configure (except some switched lines) in gcc 5.*
for these side configures missing:
-Wsign-compare -Wno-pointer-sign
Configure of ssh is the same (except the gcc version). Even the error
message looks quite strange - everything is build with -fPIC. I don't
think it was luck. Now the fail is quite deterministic.
