Subject: [ptxdist] Difficulties to compile package utils-linux while upgrading from PTXDIST-2023.09.0 to PTXDIST-2023.19.0.

Hello everybody,


my BSP still uses an old version of linux / libC, that does not provide
all modern features. 

Compiling utils-linux with PTXDIST-2023.09.0 was painless. 
Upgrading to PTXDIST-2023.11.0 caused several compilation errors.

Both PTXDIST release uses the same version of utils-linux (2.39.2) the
only difference being the build system. PTXDIST-2023.09.0 uses autotools,
while PTXDIST-2023.11.0 uses meson.

Here a list of the problems:

My linux do not provide <linux/blkzoned.h>. This causes an error while
compiling blkzone.

My linux do not provide <linux/pr.h>. This causes an error compiling blkpr.

My linux do not provide <linux/kcmp.h>. This causes an error compiling
lsfd.

My linux do not provide the symbol SIOCGSKNS in linux/sockios.h. This
causes an error while compiling test_mkfds.

In the autotool version, all these programs were disabled. This seems to
be not possible with meson.

My libC provides the symbol openpty in the libutils module. The
PTXDIST-2023.09.0 makefile util-linux.make explicitly enables libutils,
the  PTXDIST-2023.11.0 explicitly disables them.

I was able to find a solution to all the problems. Attached are my patches.
 
In meson.build I disabled build of blkzone if linux/blkzoned.h does not
exists, lsfd if linux/pr.h is missing, etc. 

In the makefile util-linux.make I just changed libutils form disabled to
enabled. Maybe one can consider to use a parameter instead.

I'm not sure if this is the best way to do, since it is my first
experience with meson. It would be nice if somebody can check them, and
maybe include them in the future versions of ptxdist.
