Fixes for kdevelop IDE integration

Script bin/gbuild-to-ide is parsing messages basing on regular
expressions.

First problem appears when used language is not English - that's why
setting LC_MESSAGES variable in Makefile.

Second problem appears with quote symbol. For me (Archlinux) script was
not working. After some investigation I found out that reason was that
my output from make included ' symbol when regular expression assumed
that it should be `. That's why using [\'`].

Example:

recipe to execute (from '/home/sadam/libreoffice/core/idlc/Executable_idlc.mk', line 28):
