Don't bake all of CC/CPP/CXX into CFLAGS

This change strips out all of the cross-compiler arguments, (-target,
-B, etc), added to ${CC}, etc via ${CROSSENV} in Makefile.inc1, so it
doesn't infect the build and subsequently the test.
Add comments noting why this logic is being added, and why the logic in

This is required after recent changes made to the toolchain to always
specify --sysroot, -target, -B, etc with clang in buildworld (presumably

Only call cpu_icache_sync_range when inserting an executable page. If the
page is non-executable the contents of the i-cache are unimportant so this
call is just adding unneeded overhead when inserting pages.
While doing research using gem5 with an O3 pipeline and 1k/32k/1M iTLB/L1
iCache/L2 Bjoern Zeeb (bz@) observed a fairly high rate of calls into
arm64_icache_sync_range() from pmap_enter() along with a high number of
instruction fetches and iTLB/iCache hits.
Limiting the calls to arm64_icache_sync_range() to only executable pages,
we observe the iTLB and iCache Hit going down by about 43%. These numbers
are quite misleading when looked at alone as at the same time instructions
retired were reduced by 19.2% and instruction fetches were reduced by 38.8%.
Overall this reduced the runtime of the test program by 22.4%.
On Juno hardware, in steady-state, running the same test, using the cycle
count to determine runtime, we do see a reduction of up to 28.9% in runtime.
While these numbers certainly depend on the program executed, we expect an
overall performance improvement.

Resolve deadlock between device_detach() and usbd_do_request_flags()
by reviving the SX control request lock and refining which lock
protects the common scratch area in "struct usb_device".
The SX control request lock was removed by r246759 because it caused a
lock order reversal with the USB enumeration lock inside
usbd_transfer_setup() as a function of r246616. It was thought that
reducing the number of locks would resolve the LOR, but because some
USB device drivers use usbd_do_request_flags() inside callback
functions, like in taskqueues, a deadlock may occur when these are
drained from device_detach(). By restoring the SX control request
lock usbd_do_request_flags() is allowed to complete its execution
when a USB device driver is detaching. By using the SX control request
lock to protect the scratch area, the LOR introduced by r246616 is
also resolved.

In existing implementations including FreeBSD, there is no reason to use
readdir_r() in the common case where potentially multiple threads each list

What's more, although readdir_r() can safely be used on FreeBSD because
NAME_MAX is forced to 255, it cannot be used safely on systems where
{NAME_MAX} is not fixed. As a concrete example, FAT/NTFS filenames can be up
to 255 UTF-16 code units long, which can be up to 765 UTF-8 bytes.
