This week's experiment build gdc with tls disabled.

[Iain Buclaw]

We really need to understand this problem first before can start 
merging Martin's shared library work into gdc.

Running testsuite:
=== gdc Summary ===

# of expected passes            13841
# of unexpected failures        1

FAIL: runnable/testaa.d execution test


Running unittests:

./libdruntime/unittest
Success!

./src/unittest
Floating point exception (core dumped)


This has me surprised.
