I think I found the problem, from the GCC install notes:

====================
sparc-sun-solaris2.10

There is a bug in older versions of the Sun assembler which breaks thread-local storage (TLS). A typical error message is

     ld: fatal: relocation error: R_SPARC_TLS_LE_HIX22: file /var/tmp//ccamPA1v.o:
       symbol <unknown>: bad symbol type SECT: symbol type must be TLS
This bug is fixed in Sun patch 118683-03 or later.

====================

>From that patch:

6728528 assembler does not handle __thread code correctly 

We're probably hitting that bug.
