Bug Description

The HWCAPS seems to be broken on PXA, because sigsetjmp of eglibc-2.14 chooses a VFP code path after the hwcaps test [1][2] which causes a SIGILL on a VSTM instruction.

How to reproduce:
1. build an arm-linux-gnueabi toolchain with eglibc-2.14
2. compile a trivial main()
3. run it with qemu-arm -cpu pxa270

Host: Debian Testing 64bit, 3.0 kernel
Command line: ~/bin/qemu/bin/qemu-arm -cpu pxa270 -L ~/bin/arm-linux-gnueabi/arm-unknown-linux-gnueabi/sysroot ./test2
Qemu version: git 1d769ceda65eef76bad3356f5b7b0ce8a61e5d76
