[PATCH] _GCC_PICFLAG: use -fPIC for s390x targets

[Mike Frysinger]

Building newer libiberty for s390x targets fails with relocation errors:
        libiberty/pic/libiberty.a(hashtab.o): In function 'htab_create':
        libiberty/hashtab.c:408:(.text+0x5e4): relocation truncated to fit:
                R_390_GOT12 against symbol 'xcalloc' defined in .text section in
                libiberty/pic/libiberty.a(xmalloc.o)
        libiberty/pic/libiberty.a(hashtab.o): In function 'htab_try_create':
        libiberty/hashtab.c:414:(.text+0x61c): relocation truncated to fit:
                R_390_GOT12 against symbol 'calloc@@GLIBC_2.2' defined in .text
                section in /lib/libc.so.6
        collect2: ld returned 1 exit status

Building with larger GOT (-fPIC rather than -fpic) fixes this.
