d1dd034d07 META_MODE: Don't rebuild build-tools targets during normal build. 
This avoids 'build command changed' due to CFLAGS/CC changes during the
normal build.  Without this the build-tools targets end up rebuilding
for the *target* rather than keeping the native versions built in
build-tools.

At least for ncurses this fixes a build error due to it trying to run

26526cb970 Signal handling within tcsh vfork code path will conflict with some system 
libraries (such as libthr) which maintain their own signal state. This
change adds the tcsh SAVESIGVEC option to save and restore the sigvecs for
the signals the child modifies before it execs.

1bdbd70599 Implement process-shared locks support for libthr.so.3, without 
breaking the ABI.  Special value is stored in the lock pointer to
indicate shared lock, and offline page in the shared memory is
allocated to store the actual lock.

cd1832fe92 Reorganize the handling all-zeroes terminal block in sparse mode 
The intent of the previous code in that case was to force
an explicit write, but the implementation was incorrect, and
as a result the write was never performed. This new implementation
instead uses ftruncate(2) to extend the file with a trailing hole.

Also introduce regression tests for these cases.
