Undebuggable meson vs numpy

[Jonathan Perkin <jperkin%pkgsrc.org@localhost>]

math/py-numpy has been broken on macOS for ages.  I had hoped a recent 
compiler upgrade would resolve it but no luck.  I tried to take a look 
to see what the actual problem is, but something is removing the build 
logs before I can look at them.

For example, from:

  https://reports.pkgci.org/Darwin/14.5/arm64/20250724.1420/py312-numpy-2.3.1/build.log

you can see there is a ".mesonpy-m8g6tta5" temporary directory, but as 
soon as the build fails it is completely removed, along with the 
meson-log.txt file that will contain the hidden errors.

This is obviously about as unhelpful as a build system can possibly be.  

I'm assuming that this isn't something that upstream are deliberately 
doing, so I'm wondering if this is something we have accidentally 
enabled somewhere?  I cannot imagine anyone would have configured this 
on purpose.

Hopefully someone has an idea to avoid me wasting hours delving into 
this.

Vive la autotools,
