It looks like our "struct shmid_ds::shm_nattch" deviates from the
standard in the sense that it is a signed integer, whereas POSIX
requires that it is unsigned, having a special type shmatt_t.
Patch up our native and 32-bit copies to use a new shmatt_t that is an
unsigned integer. As it's unsigned, we can relax the comparisons that
are performed on it. Leave the Linux, iBCS2, etc. copies of the
structure alone.

Note that keyboards are stored in an array and are not freed (just
"unregistered" by clearing some fields) so a race would be limited to
obtaining stale information about an unregistered keyboard.

This was a regression from r300349.
Setting MK_CROSS_COMPILER=no forces the compiler bootstraping *and* the
binutils/elftoolchain bootstrapping to be disabled in share/mk/src.opts.mk.
The only intent with using an external compiler is to disable bootstrapping of
the compiler. The binutils/elftoolchain bootstrapping must still occur unless
XAS is set. This did not affect WITH_SYSTEM_COMPILER.
Now that setting an external compiler sets both MK_CLANG_BOOTSTRAP and
MK_GCC_BOOTSTRAP to no, and MK_CROSS_COMPILER does the same via
share/mk/src/opts.mk, remove redundant logic that checks for
MK_CROSS_COMPILER. It will not always be true now that MK_CROSS_COMPILER==no
when an external compiler is used and --sysroot/-target is needed.

1. Always calculate what the expected values are.
2. Add 'make test-system-compiler' to show all of the computed values
vs the wanted values.
3. Extend the .info line to buildkernel/kernel-toolchain/toolchain/_cross-tools.
4. Consolidate all of the logic to one condition.

Calling it earlier increases the window when MSIX info may change.
This change does not solve the problem completely, but seems logical.
Complete solution should probably include link reset in case of MSIX
remap to trigger new negotiation, but we have no way to get notified
about that now.
Split implementation of nvram2env to generic (MI) & MIPS-based code:
- removed includes like "*siba*", because they are unused
- added nvram2env_mips.c file with MIPS-specific code, code moved from nvram2env.c
- added header file to shared defines/structures/function prototypes between MI and MIPS code
Also this fix allows to implement own nvram2env drivers.

vesa_init_done isn't a reliable guard for the mutex init. If
vesa_configure() doesn't find valid VESA info it will not set
vesa_init_done, but the lock will remain initialized. Revert r303076
and use MTX_SYSINIT to deterministically init the lock.
