configure NOK when make= parallel make

[Erick Branderhorst2]

This bug report will be sent to the Free Software Foundation,
 not to your local site managers!!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

In GNU Emacs 20.2.1 (sparc-sun-solaris2.6, Motif)
 of Tue Mar 31 1998 on hygeia.asml.nl
configured using `configure  --prefix=/app --with-x-toolkit=motif'

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

Be aware, this bug is reported about emacs 21.1

When running ./configure for emacs-21.1 I wasn't able to make src/epaths.h.
In the ./configure (./configure.in) script the following command is done:

make epaths-force

Unfortunately the environment I work in has set make to some parallel make
tool. Setting MAKE=gmake on the command line before running ./configure does
not work because `make' is hardcoded in the ./configure script.

Suggested change for ./configure.in:

2293c2293
< $MAKE epaths-force
---
> make epaths-force
