Argh, I hate the tcl build/config environment. :-(
It seems that some tools (eg: expect-5.21) use TCL_LIB_SPEC to generate
their shared library suffix. This should be .so.1.0, not .so as ld can't
use it.
Revert part of the previous change here, it did too much. libtcl75.so.1.1

AHC_SHARE_SCBS - This option attempts to share the external SCB SRAM on

The way we get a vnode for swapdev is not quite kosher. In particular
it breaks in the DEVFS_ROOT case. replicate a bit too much of bdevvp()

Use the calibrated/adjustable i8254 frequency `timer_freq' instead of
TIMER_FREQ.
Fixed missing splx() in scrn_timer(). The bug was harmless because of the
undocumented behaviour that the ipl is automatically restored for timeout
functions (see softclock()). Perhaps we should depend on this behaviour.
Fixed the ddb fix in rev.1.176. The in_debugger flag was no use because
it only works when the debugger is entered via the keyboard hotkey. The
debugger may be entered for breakpoints and traps, and the console putc
routine has no way of knowing when it was, so the console putc routine
must (almost?) always remove the cursor image.
Not fixed: console switching in ddb doesn't work (ISTR it working), and
console 0 shouldn't be switched to for the debugger hotkey unless console
0 is /dev/console.
Fixed side effects from calling add_keyboard_randomness() in the console
getc routine by not calling it. add_keyboard_randomness() currently
always reenables interrupts on 386's and 486's. This is very bad if the
console getc routine is called from the debugger and the debugger was
entered with interrupts disabled.
Fixed preservation of initial screen and now-bogus comment about it. It
was broken by setting the initial scr_buf to `buffer' instead of Crtat.
`buffer' was full of nulls and the first scroll cleared everything above
the things written through syscons.

Improved biasing of i586 clock by adjusting for hardclock() latency.
I decided to do this for every hardclock() call instead of lazily

CPU_THISTICKLEN() is now a no-op and should probably go away.
Previously it did nothing directly but had the side effect of

i586_avg_tick is too much trouble to maintain.

Increased nesting of #includes when CLOCK_HAIR is defined. This
