On modern branches there is an undocumented alias (see r219084) but on
stable/7 this is still an error.

the native sigreturn doesn't use set_mcontext like the COMPAT_FREEBSD32 version
does, this wouldn't actually result in overwriting the TLS base. Probably it
makes sense to restructure the native sigreturn to use set_mcontext for
consistency, and to allow sigreturn to change the TLS base.
TLS:
o) The mc_tls field used to store the TLS base when doing context gets and
restores was left a pointer and not converted to a 32-bit integer. This
had the bug of not correctly capturing the TLS value desired by the user,
and the extra nastiness of making the structure the wrong size.
o) The mc_tls field was not being saved by sendsig. As a result, the TLS base
would always be set to NULL when restoring from a signal handler.
Thanks to gonzo for helping track down a bunch of other TLS bugs that came out
of tracking these down.
- Fix TLS allocation for Variant I: both rtld and libc allocators
assume that tls_static_space includes space for TLS structure.
So increment calculated static size by the size of it.
and offset it only if requested by RDHWR handler. Otherwise things
get overly complicated - we need to track whether address passsed in
request for setting td_md.md_tls is already offseted or not.
Since after r232498 the ctype macros require working access to
thread-local variables, rtld crashes when libmap.conf is present.
Use hand-made isspace1() macro which is enough to detect spaces in
libmap.conf.

a loader or kernel. Specifically, kname cannot be pointed at cmd[] since
it's value is change to be an empty string after the initial call to
parse, and cmd[]'s value can be changed (thus losing a prior setting for
kname) due to user input at the boot prompt. While here, ensure that that
initial boot config file text is nul-terminated, that ops is initialized
to zero, and that kname is always initialized to a valid string.

the cross-tools stage, if CC=clang and WITH_CLANG_IS_CC is not set.
This causes no 'cc' to be installed in the temporary cross-tools tree,
making lint fall over later in the build, because it ignores ${CC} and
attempts to run 'cc' anyway.
To fix this, only skip building gcc during cross-tools, if WITHOUT_GCC
is set, or if WITH_CLANG_IS_CC is set.

For amd64 PT_GETXSTATE and PT_SETXSTATE have been redefined to match the
i386 values. The old values are still supported but should no longer be
used.
