9d8f95deca [i386][musl] Add cpuinfo to static libgcc only on *-musl* 
The __cpu_indicator_init and __cpu_model symbols are not safe to use
from shared libgcc_s.so from ifunc resolvers, so since gcc-6, only
the definitions from static libgcc.a are used, however the symbols
are kept in libgcc_s as well for backward compatibility (with
appropriate symbol version).  On targets without such backward
compatibility concern add cpuinfo to the static library only (this
avoids running the ctor, reduces libgcc_s size and elf abi concerns
about the versioned symbols).

abd0cdc9c0 Hide __cpu_indicator_init/__cpu_model from linker 
We shouldn't call external function, __cpu_indicator_init, while an object
is being relocated since its .got.plt section hasn't been updated.  It
works for non-PIE since no update on .got.plt section is required.  This
patch creates libgcc.so as a linker script, hides __cpu_indicator_init
and __cpu_model in libgcc.so.1 from linker, forces linker to resolve
__cpu_indicator_init and __cpu_model to their hidden definitions in
libgcc.a while providing backward binary compatibility.

e770bfd997 Fix i386 FP_TRAPPING_EXCEPTIONS. 
The i386 sfp-machine.h defines FP_TRAPPING_EXCEPTIONS in a way that is
always wrong: it treats a set bit as indicating the exception is
trapping, when actually a set bit (both for 387 and SSE floating
point) indicates it is masked, and a clear bit indicates it is
trapping.  This patch fixes this bug.

Bootstrapped with no regressions on x86_64-unknown-linux-gnu.

libgcc:
	* config/i386/sfp-machine.h (FP_TRAPPING_EXCEPTIONS): Treat clear
	bits not set bits as indicating trapping exceptions.
