Rework how dependency generation is performed:
...
* DPSRCS contains extra dependencies, but is _NOT_ added to CLEANFILES.
This is a change of behaviour. If a Makefile wants the clean semantics
it must specifically append to CLEANFILES.
Resolves PR toolchain/5204.
* To recap: .d (depend) files are generated for all files in SRCS and DPSRCS
that have a suffix of: .c .m .s .S .C .cc .cpp .cxx
* If YHEADER is set, automatically add the .y->.h to DPSRCS & CLEANFILES
* Ensure that ${OBJS} ${POBJS} ${LOBJS} ${SOBJS} *.d depend upon ${DPSRCS}
* Deprecate the (short lived) DEPENDSRCS
Update the various Makefiles to these new semantics; generally either
adding to CLEANFILES (because DPSRCS doesn't do that anymore), or replacing
specific .o dependencies with DPSRCS entries.
Tested with "make -j 8 distribution" and "make distribution".

Enable the libc-provided signal trampoline. The old __sigaction14

entry point has been replaced by the new __sigaction14() which is a

No shared library version change is necessary; no new symbols
are exposed outside of libc.

Clean up some rampant code duplication wrt ieee number handling:
...
- Add alignment-safe double and float unions.
- Use the above for the __infinity and __nan constants on all
architectures that use the standard ieee754 representation of
those constants.
- Add a single copy of various ieee754 math functions (frexp, isinf,
isnan, ldexp and modf) that had numerous duplicates among the
arch-specific directories.
- Use the above functions on all architectures where the generic C
versions where used. Architectures that had local assembly
routines are untouched (for those functions only).

I have no idea why this syscall wrapper does some very un-unix-like
...
argument prefrobbing, in particular, it computes max(addr, __minbrk)
and uses that. The code is like this even in the ancient libc/i386 tree,
back to the earliest rev 1.2. I did not see it Lite 1, but I'm not totally
sure what the random site I found was serving up.

* However, I do know that it should use jb and not jl.
