These tests were imported from 'glibc/elf' and are responsible for testing the TLS functionality of the dynamic loader. The file 'tls-macros-mips.h' is a copy of 'glibc/sysdeps/mips/tls-macros.h'. Dependency and link orders are critical and should NOT be changed. Even if you think you know what you are doing, do not touch the Makefile without posting to the uClibc development mailing list. -Steve
