parisc: decompressor: do not copy source files while building

Browse Source 
As commit 7ae4a78daa ("ARM: 8969/1: decompressor: simplify libfdt
builds") stated, copying source files during the build time may not
end up with as clean code as expected.

Do similar for parisc to clean up the Makefile.
