parisc: Build kernel without -ffunction-sections

hdeller · hdeller · commit 24b6c22504a2 · 2018-06-29T17:27:20.000+02:00
As suggested by Nick Piggin it seems we can drop the -ffunction-sections
compile flag, now that the kernel uses thin archives. Testing with 32-
and 64-bit kernel showed no difference in kernel size.
