9e6da10645 Run the csu tests on a DSO. This builds the tests into a shared library,
then runs these from the base test programs. With this we can check
crtbeginS.o and crtendS.o are working as expected.

532c961d02 Fix get_maxfds() in jevents
If RLIM_INFINITY == -1ULL (such as on macOS) the min() call will result
in a value of less than 1 being returned. This causes nftw() to fail
with EINVAL.

While touching this file also fix includes to work on Linux/macOS and don't
declare snprintf since it may have different attributes in the system
headers there.

These are needed for .ctors/.dtors and .jcr handling. The former needs
all the function pointers to be called in the correct order from the

This is currently disabled until __dso_handle support is added.

0c655ea2f3 Fix ncurses fallback.c build with a strict build shell
The script uses shift three times and when building with a strict /bin/sh
shifting without any arguments will cause the script to fail. In this case
the target will fail and we write an empty output file. When doing a
NO_CLEAN build after this will mean fallback.c is up to date and clang
will happily compile the empty input file which leads to strange build
errors later.

Fixed by passing three empty arguments to MkFallback.sh and only creating
fallback.c if MKfallback.sh succeeds.

6706295763 Fix regex for extracting SHM_* values for libsysdecode
There was an additional + after the {6} which is apparently ignored by the
FreeBSD regex implementation but was giving me an error when compiling on
MacOS.

While changing this also make sure that tables.h is not created if mktables
fails. The current rule would create a partial tables.h which causes following
incremental builds to use that broken file and fail with an unrelated
compilation error or even succeed even though they shouldn't.
