S390: Don't use r11 for cu-instructions as used as frame-pointer. [BZ# 32192]
Building the s390 specific iconv modules - utf16-utf32-z9.c, utf8-utf32-z9.c and utf8-utf16-z9.c - with -fno-omit-frame-pointer leads to a build error "error: %r11 cannot be used in 'asm' here" as r11 is needed as frame-pointer. The cuXY-instructions need two even-odd register pairs. Therefore the register pinning is used. This patch just uses a different register pair. Reviewed-by: Florian Weimer <fweimer@redhat.com>
