* unwind.h: Surround all visibility pragmas with #ifndef HIDE_EXPORTS.
* mklibgcc.in: Drastic restructure for comprehensibility.
Remove the old hidden-directive hack.
Eliminate support for .txt files in LIB2ADD etc (never used).
Eliminate support for assembly source files in LIB2ADDEH* and
LIBUNWIND (also never used).
Build up dependency lists for libraries incrementally.
If we have SHLIB_LINK, compile each file twice, once for the
static and once for the shared library; also probe for
-fvisibility=hidden in the generated libgcc.mk. If found,
pass that and -DHIDE_EXPORTS to the compilation of every C
source file going into the static library. If found, generate
hidden-directive lists for every assembly source file going
into the static library, but incorporate them with -include
instead of ld -r.
Write comments into generated libgcc.mk to facilitate debugging.
* Makefile.in: Pass ASM_HIDDEN_OP to mklibgcc.
* config/t-slibgcc-darwin: Define ASM_HIDDEN_OP.
* config/darwin.h (REAL_LIBGCC_SPEC): Put -lgcc back in
-Zdynamiclib case.
