Build fails on Fedora 19 because guile 2 is the default - configure should issue an error

[Frédéric Bron]

Fedora 19 comes with guile 2. However, it is possible to have both
guile 2 and guile 1.8.8 installed but the default is to point to guile
2.
configure does not complain when it finds guile 2 and the build
process can continue although the final lilypond binary fails to
compile lilypond sources. Below is an example of the output obtained
with the very simple input file containing only { c }.
The solution is to install a compatibility package
(compat-guile18{,-devel}) and set three environment variables before
issuing the configure command. For example for bash:
export GUILE=/usr/bin/guile1.8
export GUILE_CONFIG=/usr/bin/guile1.8-config
export GUILE_TOOLS=/usr/bin/guile1.8-tools

When this is not done, configure should issue an error like:
error: guile version should be > 1.X.Y and < 2.0.0 but 2.0.Z found.
