two simple flex and bison patches

[Thomas Vander Stichele <thomas apestaart org>]

Hi,

since lots of people get errors during the build of libIDL in garnome 
because of missing flex, I've made two really small patches to 
configure.in in two modules that check and fatally fail during configure 
if these are missing.

I'm posting them here because it'd sure be nice if they got in before 
2.0.2 and the next garnome, instead of lying around for weeks.  They're 
pretty trivial, but I don't have any experience on non-i686-linux boxes so 
please take a quick look at it to make sure they also look right for 
solaris and others.

Thanks,
Thomas
