Configure et al: treat C defines separately

With some compilers, C macros are defined differently on the command
line than on Unix.  It could be that the flad to define them isn't -D,
it could also be that they need to be grouped together and not be mixed
in with the other compiler flags (that's how it's done on VMS, for
example).

On Unix family platform configurations, we can continue to have macro
definitions mixed in with the rest of the flags, so the changes in
Configurations/*.conf are kept to an absolute minimum.

libraries into the final program.
cflags => Flags that are used at all times when
compiling.
defines => As an alternative, macro definitions may be
present here instead of in `cflags'. If
given here, they MUST be as an array of the
string such as "MACRO=value", or just
"MACRO" for definitions without value.
debug_cflags => Extra compilation flags used when making a
debug build (when Configure receives the
--debug option). Typically something like
"-g -O0".
debug_defines => Similarly to `debug_cflags', this gets
combined with `defines' during a debug
build. The value here MUST also be an
array of the same form as for `defines'.
release_cflags => Extra compilation flags used when making a
release build (when Configure receives the
--release option, or doesn't receive the
--debug option). Typically something like
"-O" or "-O3".
release_defines => Similarly to `release_cflags', this gets
combined with `defines' during a release
build. The value here MUST also be an
array of the same form as for `defines'.
thread_cflags => Extra compilation flags used when
compiling with threading enabled.
Explained further below. [2]
thread_defines => Similarly to `thread_cflags', this gets
combined with `defines' when threading is
enabled. The value here MUST also be an
array of the same form as for `defines'.
shared_cflag => Extra compilation flags used when
compiling for shared libraries, typically
something like "-fPIC".
