This update for gcc43 fixes the following issues:
This update adds support for 'expolines' on s390x, allowing fixing CVE-2017-5715 in a more lightweight fashion. (bsc#1086069)
The option flags are the same as for the x86 retpolines.
A compiler crash when building userland packages with x86 retpolines was fixed. (bsc#1092807)
