Sorry, I meant to say that it allows me to manually specify the path
to the proper freetype-config script.  You are correct that configure
detects the system's native script by default, since it appears first
in $PATH.

I was referring to the behavior of overriding the AC_CHECK_PROGS
variable with configure arguments or environment variables.  The patch
allows:

        FREETYPE=/cross-stuff/bin/freetype-config ./configure ...

or

        ./configure FREETYPE=/cross-stuff/bin/freetype-config ...

which will then build the grub-mkfont utility with the proper system's
libraries.

Thanks.
