AIX 5.3 does not support TLS, so there are pieces not implemented in
config/rs6000/aix53.h. Jakub's configuration probably will not work.

Also, GNU Binutils does not support AIX TLS or AIX 6.1/7.1, but you should not
need Binutils to reproduce.

rs6000_delegitimize_address() assumes the symbol is in the constant pool
because all TOC symbols are in the constant pool.  I thought that I associated
the LCM symbol with the matching LC symbol, but that was in a different
iteration of the patches. It probably needs a check for
CONSTANT_POOL_ADDRESS_P().
