[PATCH] Use IE model for static variables in glibc

[Roland McGrath]

The tests should have comments explaining what they are testing.

If it's important that all TLS accesses in libc code be IE, then there
should be a static test for that.  Perhaps it could grep readelf -r output
for the TLS dynamic reloc types.  Or perhaps there is something we could do
to make references to __tls_get_addr when linking libc.so be a hard failure.

If the intent is to catch all TLS access in libc code, then why are you
touching the source instead of just compiling with -ftls-model=initial-exec
across the board?  If we do that, then it's probably fine not to have the
static test.


Thanks,
Roland
