I don't see any indication that gdb.base/break-interp.exp is disabled
by default, though it is part of the slow_tests list so if you don't
run slow tests then it would not show up.  I actually have four tests
that fail due to prelink:

gdb.base/attach-pie-misread.exp
gdb.base/break-interp.exp
gdb.base/prelink.exp
gdb.threads/dlopen-libpthread.exp

It also seems to get used in:

gdb.server/connect-stopped-target.exp
gdb.server/solib-list.exp
gdb.base/nostdlib.exp
gdb.base/relativedebug.exp
gdb.base/solib-overlap.exp

Although those did not show up in my FAIL list.

Should we just remove all the gdb tests that use prelink?
