 	src/libexec/ld.elf_so: tls.c xmalloc.c
 
 Log Message:
 ld.elf_so: Fix static TLS alignment on variant II platforms.
 
 Only affects obscure architectures like x86, though.
 
 Sprinkle assertions to make sure this breaks in other ways on other
 architectures too, like variant I, or variant II with _lwp_gettcb().
 Fair's fair, right?
 
 XXX We should consider verifying that every Elf_Phdr::p_align is
 reasonable (i.e., is a power of two, or is zero but only if p_memsz
 is also zero), and that p_filesz <= p_memsz, in headers.c for the
 main object and in map_object.c for other objects.
