[PATCH] comptools/make: Install 'gmake' symlink

[Bernhard Walle]

We had following problem: We're building a toolchain with an old glibc
version for compatibility with old Linux distributions (glibc 2.9). This
version requires make < 4 to build. However, the configure script of
glibc looks for make in the order "gnumake", "gmake" and "make". So when
"gmake" is available in the system (which is the case on Gentoo Linux
per default, unfortunately), then configure finds the system gmake 4.1
instead of the ct-ng make 3.82.

This patch adds an option to install a symlink so that 'gmake' is also
available in the old version when building toolchains.

v2: Add an option instead of always installing the symlink
