(that was formerly only used for HOST_CYGWIN.).
Clean up implementation to minimise unnecessary variable munging.
Ensure all .dep files are deleted in cleandepend:.
This allows us to correctly support CPPFLAGS.<file> in make depend, and
whilst this method is marginally slower in the "no existing .depend file"
case, it should be faster in the "rebuilding depend for a subset of
source files" case.
Clarify that command-line overrides of the MKxxx variables should be
done via the environment rather than make(1) command-line variable
assignment, since the latter doesn't actually work as intended.
only list the (often complicated) ${COMPILE.*} rules once always building
to ${.TARGET}.tmp. Then, depending on whether *OPTS has -g, either
"mv ${.TARGET}.tmp ${.TARGET}" or "${LD} -[xX] -r ${TARGET}.tmp -o ${.TARGET}"
as appropriate.
This can prevent inconsistency that could occur between "echo ${COMPILE.*:Q}"
and "${COMPILE.*}", such as the problem in rev 1.226. (There were still
examples of this in .cc.so and .m.so !!!)
Remove `@' from most non-echo rules, so that we can actually see what's
happening. This helps debugging problems, such as that fixed by rev 1.226.
Always remove all possible temp files that might occur because of the above.
Be consistent about ${CC} instead of $(CC)
* translate MSG_* flags
* rewrite CMSG level/type to appropriate NetBSD value on input, and to Linux
value on output
* handle different CMSG_DATA alignment for some archs
This fixes SCM_RIGHTS passing. Other SCM_* types are not supported -
the set is different on NetBSD and Linux. SCM_TIMESTAMP doesn't seem
to be actually implemented in Linux 2.5.15, so it's not supported
for Linux binaries either (for now).

includes. for GCC3, set this to -I instead of -isystem.
XXX this should really be either not required or a -isystem-cxx, but for
now this is required to build libstdc++-v3, which otherwise complains
heavily about STL headers not being C code(!)
XXX: sun2 seems to be currently generally busted but most of the world
builds. of course it is untested..
XXX: sh3* and -pg goes BOOM with gcc3.3... it generates code that uses
the same labels twice... need to set NOPROFILE for now.
to determine TARGET_ENDIANNESS.
This should fix problem reported privately by Matt Green <mrg@>.
This uses exists(${CC:ts::C/:.*$//}) as we don't expect the command name to
contain `:'. (The ":ts" trick is from a discussion with Simon Gerraty <sjg@>.)
