FTBFS with glibc 2.34

[Sergio Durigan Junior]

guile 3.0.7-1 is currently FTBFS'ing with glibc 2.34:

In file included from regexec.c:1368,

This is happening because of a bug in gnulib which has since been fixed upstream. This is currently causing guile-3.0 to be stuck in -proposed.

This has been reported upstream here:

https://debbugs.gnu.org/cgi/bugreport.cgi?bug=49930

and fixed upstream by the following commit:

http://git.savannah.gnu.org/gitweb/?p=guile.git;a=commitdiff;h=b4a80f4239b19fea4d2cc3e9d197f24b809f0624

I considered backporting the commit to fix the issue in Ubuntu, but it's a really large diff and I think it's OK to wait a bit more and see if upstream will release a new version containing the fix.
