Jason A. Donenfeld 4b058c9f28 powerpc/vdso: allow r30 in vDSO code generation of getrandom 
For gettimeofday, -ffixed-r30 was passed to work around a bug in Go
code, where the vDSO trampoline forgot to save and restore this register
across function calls. But Go requires a different trampoline for every
call, and there's no reason that new Go code needs to be broken and add
more bugs. So remove -ffixed-r30 for getrandom.

Fixes: 8072b39c3a ("powerpc/vdso: Wire up getrandom() vDSO implementation on VDSO64")
