Log Message:
End libc Makefile .${PARSEDIR} abuse

It is pointless assigning ${.PARSEDIR) to a variable using '='
as when that variable is later expanded, ${.PARSEDIR} will not
have a value, and we end up with things like:

        .... -I. -I/home/source/ab/HEAD/src/lib/libc/arch/mips/softfloat
        -I -DSOFTFLOAT_FOR_GCC
        -I/home/source/ab/HEAD/src/lib/libc/arch/mips/softfloat
        -I -DSOFTFLOAT_FOR_GCC
        -DSOFTFLOAT -I/home/source/ab/HEAD/src/sys ....

That exxtracted from a failing command from the autobuilds (which I
first saw on my local system attempting a mips64eb build).   That is
all part of one (long) command line from which I extracted that piece
(and then manually line wrapped it for this log message).

Note the 2nd and 4 lines ... those are meant to have ${.PARSEDIR}
between the -I and -D (I doubt there is a "./-DSOFTFLOAT_FOR_GCC"
directory to include anything from).   Or rather, they do, but
it is expanding to nothing when the command is run (no makefile is
then being parsed).

So, invent a bunch of new variables to be assigned the value of
${.PARSEDIR} using := so the assignment happens while the Makefile
is being parsed, and then use the new variables in other variable
assignments which had been using ${.PARSEDIR}

Someone should check, fix, and clean up all this ... the world has
descended to a truly perilously dangerous place when I start hacking
on Makefiles.
