* sysdeps/generic/libc-tls.c (__libc_setup_tls): Don't check for
PT_LOAD program headers and don't try to relocate PT_TLS's p_vaddr; it is already absolute. * elf/Makefile (tests): List tst-tls1 and tst-tls2 unconditionally. [$(build-static) = yes] (tests): Add tst-tls1-static, tst-tls2-static. [$(build-static) = yes] (tests-static): New variable. ($(tests-static):%=$(objfpx)%.o)): New static pattern rule.
