A number of things seem to have broken all at once. Commenting out that static_assert leads to a bug in src/locale.cpp about switching on '-1' on a switch on size_t in two places. Fixing that bug (by replacing -1 and -2 with (size_t)-1 and (size_t)-2, which is hopefully right.
Fixing that leads to lining producing:
ld: bad codegen, pointer diff in __ZSt17__throw_bad_allocv to global weak symbol __ZTISt9bad_alloc for architecture i386
Rather than try to debug this myself, I'm tempted to leave it to more experienced people.
One problem that this has shown me is that the recommended way of building libcxx (symlinking the svn directories into /usr/include and /usr/lib) means that if you svn update the library and it won't build, you are left with a totally non-functional library.
