Modified Files:
        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.

PR bin/60469: bin/60469: assertion "ALIGNED_P(q, obj->tlsalign)"
failed: file "/usr/src/libexec/ld.elf_so/tls.c", line 333
