Determining the name of Guile commands

Determining the name of Guile commands

Hello!

I noticed there’s no reliable way to determine the name of the ‘guild’
or ‘guile’ command in the face of --program-suffix et al. (a situation
likely more frequent during the transition from 2.0 to 2.2.)

So I thought about adding new variables to the .pc file:

Then GUILE_PROGS should be adjusted accordingly.

WDYT?

If there are no objections, I’ll implement and document that one of
these days.

Done in 5fac1a7.

For the record, GDB has been using this (then unimplemented) feature for
some time already:
<https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=blob;f=gdb/acinclude.m4#l473>.

Comments welcome!
