ARC/signal: shield sa_restorer from compiler toggle side-effects

when building uClibc with -O0 (DODEBUG build) the default sigrestorer had some extra glue code generated for stack manipulation which was messing up resume from signal path.

So annotate the function with -Os so that gcc would only generate the bare min 2 instruction TRAP sequence

Add support for R_ARC_NONE relocations.

The R_ARC_NONE relocation is generated when --gc-sections, used by the compile time linker, removes some sections. This is completely normal, and we can see that all other targets (based on random sampling) have support for R_*_NONE relocations (named for each target).

Handling R_ARC_NONE involves doing nothing with it, which is nice and easy.

ldso: mark _dl_exit as noreturn

Otherwise gcc might not understand that oom() ended control-flow and might emit an (untaken) reference to abort() in _dl_update_slotinfo() on e.g. SH4 which breaks linking ld-uClibc.so. Arguably -ffreestanding should prevent GCC from emitting this '.global abort' but alas, it does not, which is another bug..

Also mark the function cold to further lower the incoming frequency and branch probability.

utmp: favour POSIX utmpx over SVID utmp

Note: _PATH_UTMPX == _PATH_UTMP and the utmp struct is identical to the utmpx struct so this only changes the external API entrypoints and NOT the underlying data source.

This saves about 500b (~1300b from previously ~1950) while at it.
