description:
Remove options (NVNODE, NBUF, and BUFPAGES) for small RAM machines.

These options make extracting binary sets much slower even on miniroot.
Instead, use "options BUFCACHE=5" (use 5% of memory for buffercache) and
also specify "-fno-unwind-tables" for COPTS to shrink INSTALL kernel.

Worth to pullup to netbsd-9.
