This changes almost all the "gnomehack" only USE_GNOME cases to USES= pathfix.
If a port used other USE_GNOME items it was untouched.
The ports that used other USES were fixed by hand.

liburcu is a LGPLv2.1 userspace RCU (read-copy-update)
library. This data synchronization library provides
read-side access which scales linearly with the number
of cores. It does so by allowing multiples copies of a
given data structure to live at the same time, and by
monitoring the data structure accesses to detect grace
periods after which memory reclamation is possible.
