debug files for userland programs and libraries. The "-g" debug flag
is automatically applied when WITH_DEBUG_FILES is set.
The debug files are now named ${prog}.debug and ${shlib}.debug for
consistency with other systems and documentation. In addition they are
installed under /usr/lib/debug, to simplify the process of installing
them if needed after a crash. Users of bsd.{prog,lib}.mk outside of the
base system place the standalone debug files in a .debug subdirectory.
GDB automatically searches both of these directories for standalone
debug files.
Thanks to everyone who contributed changes, review, and testing during
development.
The build system is really intricate and I had a hard time to remind the
whole picture even when reading my own words. This one will hopefully
be better.

To speed build times, if XCC is an absolute path or

This compiler flag enforces that that people either mark variables
static or use an external declarations for the variable, similar to how
-Wmissing-prototypes works for functions.
Due to the fact that Yacc/Lex generate code that cannot trivially be
changed to not warn because of this (lots of yy* variables), add a
NO_WMISSING_VARIABLE_DECLARATIONS that can be used to turn off this
specific compiler warning.

Change the default compiler for little-endian ARM to clang to allow for more
testing before 10.0 is released. As LLVM and clang currnetly lack support
for big-endian ARM leave gcc as the default there.
This will also allow us to investigate moving to use the hard floating-point
version of the ARM EABI on SoCs that include the Vector Floating Point unit.
A version of this is included in all ARMv6 and ARMv7 SoCs we currently, and
are likely to support.
Both the current ABI and the new EABI are supported by clang and it will be
built correctly depending on which is selected by the user.
This avoids having separate cases in the install rule for PROGNAME set and
not set. This is a minor cleanup in advance of further support for
standalone debug files.

Without all those three, the clang binary shrinks (x86_64) from ~36MB
to ~32MB (unstripped).
To disable these clang components, and get a smaller clang binary built
and installed, set WITHOUT_CLANG_FULL in src.conf(5). During the
initial stages of buildworld, those extra components are already
disabled automatically, to save some build time.
