re PR target/22209 (libgfortran unresolvable symbols on irix6.5)
* libgcc2.c (MIN_UNITS_PER_WORD): Move default definition from
libgcc2.h.
(LIBGCC2_UNITS_PER_WORD): Provide default definition, using old
MIN_UNITS_PER_WORD logic from libgcc2.h. Do nothing if
LIBGCC2_UNITS_PER_WORD > MIN_UNITS_PER_WORD.
* libgcc2.h (MIN_UNITS_PER_WORD): Remove definition from here.
Use LIBGCC2_UNITS_PER_WORD rather than MIN_UNITS_PER_WORD to
determine the size of Wtype, etc.
* mklibgcc.in (LIB2_SIDITI_CONV_FUNCS): New argument.
(swfloatfuncs): New variable.
(dwfloatfuncs): Likewise.
(lib2funcs): Remove floating-point conversion functions from
initial assignment. Use LIB2_SIDITI_CONV_FUNCS to determine
the set of conversion routines needed. Allow entries to specify
an object name, filename and word size. Update users accordingly.
* Makefile.in (libgcc.mk): Pass LIB2_SIDITI_CONV_FUNCS.
* config/mips/t-mips (LIB2_SIDITI_CONV_FUNCS): Define.
