Quoting 56211a166a "fdo#72394 Don't endlessly
expand $(share_subdir_name) into itself":
* The compile-time variable LIBO_SHARE_FOLDER should not end up as a runtime
framework path variable, esp. since accidentally re-substituting it for
"share" segments in unrelated URLs like <file:///export/share/for-all> does
not make sense. ac4e19f908 "fdo#68552: Don't
(attempt to) do run-time expansion of build-time parameters" had already
attempted a fix for that, but it had to be reverted again with
791a8b96f7 because it "Unfortunately does not
work if BUILDDIR is different from SRCDIR."
So this time fix it not via configure-expanded *.in files, but via xsltproc
(for officecfg/registry/ files) and sed (for wizards/soruce/configshare files).
The changes to officecfg/util/alllang.xsl will replace @LIBO_SHARE_FOLDER@ only
in oor:name attribues (and in <value> text), not in any other attributes,
because I have no idea how to write that generically in XSLT and it happens to
be only needed in oor:name for now.
