MatN,
If you are modifying configure.ac anyway, I suggest to comment out the
line about "no-unknown-warning-option" ?
It causes no end of useless warnings.
Good suggestion. It will be done. 

Also, the detection of the number of cpus (about line 143) is done by a
very specific Linux method /proc/cpuinfo) , which does not work on
FreeBSD and macOS.
So I do an exact replacement from:
      CPUS=`grep -c "^proc" /proc/cpuinfo`
to:
      CPUS=`nproc`
Is that correct?

Andrew,
For     0031-configure-script-specially-for-termux.patch   is it acceptable to use the filename of "configure_termux" instead of "my_configure"?    I was already thinking about adding "configure_32-bit" to make it easier when I create AppImages.

sure, you can also put it in blds directory like all other build scripts...
