rS320470: Start to remove _libc_arm_fpu_present checks. We don't support the VFP on

Summary

We don't support the VFP on ARMv4 or ARMv5, and only support it when
it's present on ARMv6 and later. As such always store the VFP register
in setjmp and restore them in longjmp when building for armv6.

With this change I can link almost all of 32-bit arm userland with lld. There are multiple issues in boot, but most likely it's just -znotext needed, and one or two others.
