Work around a SPARC glibc bug which caused the epoll_create1 configure

SPARC glibc provided the function in the library but didn't declare

The problem stems from two things:

kvmclock is represented by two feature bits. Therefore, lookup_feature

accordingly and switch to a bool return type at this chance.

Newer kernels are large enough that they can overlap the address
where qemu places the initrd. Move the initrd up so that there is
enough space for the kernel again.
Unfortunately it's not possible to automatically determine the
