 Stefan> For example:

 Stefan> Without this fix. NSPR would return /usr/ as it's prefix which is

 Stefan> Correct would be $(STAGING_DIR)/usr.

 Stefan> All packages that have <pkg>_INSTALL_STAGING = YES defined and
 Stefan> also install some config file(s) into $(STAGING_DIR)/usr/bin must
 Stefan> hereafter also define <pkg>_CONFIG_FIXUP with the correspondig
 Stefan> filename(s).

Committed, thanks.
