alpha: unbreak OSF/1 (a.out) binaries
OSF/1 brk(2) was broken by following one-liner in sys_brk() (commit 4cc6028d4040f95cdb590a87db478b42b8be0508): - if (brk < mm->end_code) + if (brk < mm->start_brk) goto out; The problem is that osf_set_program_attributes() does update mm->end_code, but not mm->start_brk, which still contains inappropriate value left from binary loader, so brk() always fails.
