In some cases, one might want to generate some source files from
others, that's done as follows:
GENERATE[foo.s]=asm/something.pl $(CFLAGS)
GENERATE[bar.s]=asm/bar.S

Configure places no rules on the command line, except the the first
item muct be the generator file. It is, however, entirely up to the
build file template to define exactly how those command lines should
be handled, how the output is captured and so on.

The thread_cflag setting filled a double role, as kinda sorta an
indicator of thread scheme, and as cflags. Some configs also added
lflags and ex_libs for multithreading regardless of if threading would
be enabled or not.
Instead of this, add threading cflags among in the cflag setting,
threading lflags in the lflag setting and so on if and only if threads
are enabled (which they are by default).
Also, for configs where there are no special cflags for threading (the
VMS configs are of that kind), this makes it possible to still clearly
mention what thread scheme is used.
The exact value of thread scheme is currently ignored except when it's
"(unknown)", and thereby only serves as a flag to tell if we know how
to build for multi-threading in a particular config. Yet, the
currently used values are "(unknown)", "pthreads", "uithreads" (a.k.a
solaris threads) and "winthreads".

Although I explicitly don't care about the tinfoil-hat reason given in

filenames from the compiled binary.
The two reasons we do care about in the context of firmware such as EDK2
are that it allows for a smaller footprint, and it is also a necessary
component of a binary-reproducible build.
To that end, introduce OPENSSL_FILE and OPENSSL_LINE macros, defining
them to __FILE__ and __LINE__ respectively in the normal case, but to
"" and 0 when OPENSSL_NO_FILENAMES is set.
This is mostly a naïve invocation of
