Yang Yujie 227b18f5d7 LoongArch: Reimplement multilib build option handling.
Library build options from --with-multilib-list used to be processed with
*self_spec, which missed the driver's initial canonicalization.  This
caused limitations on CFLAGS override and the use of driver-only options
like -m[no]-lsx.

The problem is solved by promoting the injection rules of --with-multilib-list
options to the first element of DRIVER_SELF_SPECS, to make them execute before
the canonialization.  The library-build options are also hard-coded in
the driver and can be used conveniently by the builders of other non-gcc
libraries via the use of -fmultiflags.

Bootstrapped and tested on loongarch64-linux-gnu.

ChangeLog:

	* config-ml.in: Remove unneeded loongarch clause.
	* configure.ac: Register custom makefile fragments mt-loongarch-*
	for loongarch targets.
	* configure: Regenerate.

config/ChangeLog:

	* mt-loongarch-mlib: New file.  Pass -fmultiflags when building
	target libraries (FLAGS_FOR_TARGET).
	* mt-loongarch-elf: New file.
	* mt-loongarch-gnu: New file.

gcc/ChangeLog:

	* config.gcc: Pass the default ABI via TM_MULTILIB_CONFIG.
	* config/loongarch/loongarch-driver.h: Invoke MLIB_SELF_SPECS
	before the driver canonicalization routines.
	* config/loongarch/loongarch.h: Move definitions of CC1_SPEC etc.
	to loongarch-driver.h
	* config/loongarch/t-linux: Move multilib-related definitions to
	t-multilib.
	* config/loongarch/t-multilib: New file.  Inject library build
	options obtained from --with-multilib-list.
	* config/loongarch/t-loongarch: Same.

This directory contains the GNU Compiler Collection (GCC).

The GNU Compiler Collection is free software.  See the files whose
names start with COPYING for copying permission.  The manuals, and
some of the runtime libraries, are under different terms; see the
individual source files for details.

The directory INSTALL contains copies of the installation information
as HTML and plain text.  The source of this information is
gcc/doc/install.texi.  The installation information includes details
of what is included in the GCC sources and what files GCC installs.

See the file gcc/doc/gcc.texi (together with other files that it
includes) for usage and porting information.  An online readable
version of the manual is in the files gcc/doc/gcc.info*.

See http://gcc.gnu.org/bugs/ for how to report bugs usefully.

Copyright years on GCC source files may be listed using range
notation, e.g., 1987-2012, indicating that every year in the range,
inclusive, is a copyrightable year that could otherwise be listed
individually.
