bug#9789: [patch] adding the option --without-compress-el to configure

[OKAZAKI Tetsurou]

Hi,

On Cygwin with low voltage notebooks, `make install' takes long time
to compress the Lisp source files.

Attached patch adds new configure option `--without-compress-el' which
suppresses automatic compression of the *.el files.
