to kernels build now (this breaks due to current -current breakage.)
(i guess christos's csu fixes fixed the builds libgcc_s build, which was
missing symbols that i recall as being weak.)
the mips* binaries are as-yet untested.

* ppcnbsd-tdep.c (ppcnbsd_return_value): Change type of last two
arguments from void * to gdb_byte *.
- disable rules for gengtype-yacc.c, gengtype-yacc.h and gengtype-lex.c
- pull across a fix for cygwin building fixincludes from GCC3 tree
- disable %.info rules.

- add GPLUSPLUS_BACKWARD_INCLUDE_DIR to the INCLUDE_DEFAULTS includes
- define GPLUSPLUS_BACKWARD_INCLUDE_DIR, TOOLDIR_BASE_PREFIX,
STANDARD_BINDIR_PREFIX and STANDARD_LIBEXEC_PREFIX
- delete NETBSD_LIBGCC_SPEC
- define LIBGCC_PICSUFFIX as "_pic".
