From scratch meaning glibc alone or the whole toolchain. I used buildroot and
glibc-dirclean to nuke entire glibc but gcc was not rebuilt. I can try that too.
Some of the failed tests have prints about static TLS block ... so I'm wondering
if they could be related ?
| $ cat dlfcn/tststatic.out
| .../build/libc.so.6: cannot allocate memory in static TLS block
Also while we figure this out, does this prevent ARC port from being committed. It
is a functioning system otherwise: I'm doing doing cross run of testsuite with
sshd etc involved and these addition 10+ failures don't seem to be getting in the way.
