Darwin: Place global inits in the correct section.
This handles placement of global initializers into __TEXT,__StaticInit as used
by other platform toolchains.
Signed-off-by: Iain Sandoe <iain@sandoe.co.uk>
gcc/ChangeLog:
* config/darwin-sections.def (static_init_section): Add the
__TEXT,__StaticInit section.
* config/darwin.cc (darwin_function_section): Use the static init
section for global initializers, to match other platform toolchains.
