Log Message:
mkfontscale: update to 1.2.3.

This release switches to the use of pkg-config to find the zlib library.
For platforms like darwin that don't ship zlib.pc, you can specify
ZLIB_CFLAGS and ZLIB_LIBS in the build environment to bypass this.

For those building for 32-bit platforms, it also enables use of the
"large file" APIs - while font files should never be more than 2gb in size,
they may be stored on filesystems with large inodes.

Since this release was generated using the new GNU autoconf 2.72, this
also adds a --enable-year2038 configure flag which may allow mkfontscale
to work with files whose timestamps are later than January 19, 2038, but
this has not been tested.
