printf %ld regression from 20200725a to 20200731 on 32-bit big-endian platforms

[zv-io]

On 32-bit big-endian platforms (such as ppc or sparc), there was a regression in the printf %ld format specifier. Minimal reproducer:

# 32-bit ppc and sparc
$ echo 1 | awk '{printf "%d\n%ld\n", $1,$1}'
1
0

# 32-bit x86, arm, etc.
$ echo 1 | awk '{printf "%d\n%ld\n", $1,$1}'
1
1

I can provide access to a 32-bit PowerPC or SPARC environment, though QEMU user may be sufficient for debugging/testing.

agreed - Zach van Rijn sent mail about this on April 19. I was able to reproduce the problem, and intend working on mawk once I'm done with fixes for byacc.

The relevant change-log item is indeed Debian #303825 though the relationship could use a couple of lines for clarity. I'll do that. At the moment, I'm studying a (simple) fix for this problem.
