fix _NSIG for it. better document what's going on in sigaction(). seems to not induce any actual code changes (sans mips).

2008-11-25- Fix thumb2 PIE (Joseph S. Myers)Bernhard Reutner-Fischer
This patch fixes position-independent executables (PIEs) for Thumb-2. In Thumb assembly, instructions reading pc give a value 4 greater than the address of the instruction, rather than 8 greater as in ARM mode, so the offset to the GOT needs to have the right offset. (The Thumb-1 code already gets this right; it's the code shared by ARM and Thumb-2 that needs fixing.)

2008-10-19- fix sigaction on older kernels (Michael Deutschmann)Bernhard Reutner-Fischer
In issue #5554 Michael wrote: The implementation of sigaction on i386 for older kernels makes the system call using an inline asm element with two flaws: 1. The asm is not marked as depending on the kact structure or modifying the koact structure. Thus, GCC is free to assume these structures need not be kept consistent, allowing it to remove all initialization of kact. 2. The asm allows the signal number to be provided as a memory reference. But this allows GCC to provide a stack-relative operand, which will break because the assembler saves %ebx on the stack before using that operand. 1 didn't use to be a problem in practice because GCC 4.2.* didn't seize the optimization opportunity. GCC 4.3.2, however, optimizes out the "kact.sa_flags = act->sa_flags | SA_RESTORER;" line, so that the kernel sees garbage in sa_flags. This can result in the kernel seeing the SA_RESETHAND flag, causing erratic behaviour in signal dependent programs. 2 becomes an issue if "-fomit-frame-pointer" is provided. In uClibc-0.9.29 it isn't, uClibc-0.9.30-rc2 does use the flag by default.
