[Libreoffice] build only xpcom in moz: not working

Hi,

In your commit 291b85778669b4e4e276faab22add9d0e80046df
(Build our mozilla (module moz) against the nss we have built anyway.)

This hunk:

Does not do what you intend from it.

1) Not robust: if the cd fails, the next command (make) is run
   anyway. Please use "&&" instead of ";" when chaining commands.

2) solenv/inc/tg_ext.mk prepends "cd $(P_BUILD_DIR) && " when calling
   BUILD_ACTION, so what is done is e.g.:

   cd misc/build/mozilla/X_objdir && cd mozilla/X_objdir/xpcom ; $(GNUMAKE) -j$(EXTMAXPROCESS)

   the second cd fails and thus make is executed in X_objdir and not
   in xpcom.

   Doing make only in xpcom fails from a clean state (some files that
   are needed are not built), so I've completely reverted that hunk for
   now. Feel free to do whatever you meant by this hunk in a way that
   works :)
