Darwin: Handle linker '-demangle' option.
Most of the Darwin linkers in use support this option which we will now pass by default (matching the Xcode clang impl.)> Signed-off-by: Iain Sandoe <iain@sandoe.co.uk> gcc/ChangeLog: * config.in: Regenerate. * config/darwin.h (DARWIN_LD_DEMANGLE): New. (LINK_COMMAND_SPEC_A): Add demangle handling. * configure: Regenerate. * configure.ac: Detect linker support for '-demangle'.
