Remove -g from static test runs.

It fails on OS X when the object file was generated with trunk llvm.
Generating the binary is fine, but building the dSYM folder fails
with assertion:

Assertion failed: (linked_addr_pos != line_table_map.end()), function FixReferences, file /SourceCache/dwarf_utilities/dwarf_utilities-119/source/DWARFdSYM.cpp, line 3749.

I'm hoping this problem will magically fix itself with either an llvm or
dsymutil update.
