librt.so fails to load

Hello all,
I'm using uClibc-0.9.29 for ARM. I compiled and loaded PHP which
requires librt.so.
When ldso tries to load librt.so, it fails with "Can't modify
librt.so's text section. Use GCC option -fPIC for shared objects,
please".
I tracked the print in the code. It's in dl-elf.c under:
if (dynamic_info[DT_TEXTREL]) {
....
_dl_dprintf(_dl_debug_file, "Can't modify %s's text section. Use GCC
option -fPIC for shared objects, please.\n",libname);
_dl_exit(1);
However, I did compile librt with -fPIC and when I objdump -x it, I
see that:
Dynamic Section:
NEEDED libc.so.0
SONAME librt.so.0
HASH 0x134
STRTAB 0x414
SYMTAB 0x204
STRSZ 0x15e
SYMENT 0x10
PLTGOT 0x9000
PLTRELSZ 0x20
PLTREL 0x11
JMPREL 0x57c
REL 0x574
RELSZ 0x8
RELENT 0x8
TEXTREL 0x0
So TEXTREL is not set.
Is anyone aware of a bug in ldso that would cause that? Any other
suggestions?
