Provide the FreeBSD implementation for _UI_siglongjmp_cont on x86.
On FreeBSD, _NSIG is at least 128, so just pass a pointer to the
signal mask in the register.
Add my copyright.

Fix compilation on non-glibc machines.
Commit 297d9cd07d7ea9b541fb13bffe418 (Fix for failing test-setjmp)
breaks non glibc systems, since __GLIBC_PREREQ is not defined there.
As a consequence, preprocessor aborts with an error.
Trying to hide __GLIBC_PREREQ under #ifdef __GLIBC would require
either code duplication, or moving the longjmp implementation into
the separate file, which is included twice. In fact, I am not sure
in any use of the __GLIBC_PREREQ at the compile time, because the
compiled code can be run on the later version of glibc.
Below is the patch, tested on FreeBSD x86/x86_64 and Scientific Linux 6.1
x86_64. I compile the code always, but keep it in under unused static
symbol. In principle, the code could be optimized out by linker.

The problem is actually two-fold:
First, the loops in {sig,}longjmp.c are "do { ... } while (unw_step() >= 0);"
But unw_step() returns 0 on reaching the end of the chain (_start),
and the loop should stop there.
The second problem is that with this commit:
http://repo.or.cz/w/glibc.git/commitdiff/c67da0b50e3d20f89d7bb352cd67dcf66d808e50
glibc obfuscates value of SP in jmp_buf, so we might as well just give up.
Patch attached.
Thanks,

Make setjmp/longjmp work at least on FreeBSD/amd64.
FreeBSD-supplied setjmp() saves incremented stack pointer into jmpbuf.
I have no idea whether siglongjmp ever worked on amd64, since
UNW_NUM_EH_REGS == 2 and abort at siglongjmp.c:81 is firing.

Add initial ARM and MIPS support. To support this, also enable the
reading of .debug_frame sections (used in lieu of .eh_frame sections
when they're not available).
