Same here.

xcrun: error: unable to find utility "m4", not a developer tool or in 
PATH

$ xcrun -find lex
/Library/Developer/CommandLineTools/usr/bin/lex

So this is good triangulating information: you've got what looks to be a 
full Xcode install, where the things in question currently ain't broke, 
whereas I've got no Xcode, only the standalone Command Line Tools:

$ pkgutil --pkg-info=com.apple.pkg.CLTools_Executables | grep ^version:
version: 15.3.0.0.1.1708646388

> $ m4 --version
> GNU M4 1.4.6

$ m4 --version
xcode-select: Failed to locate 'm4', requesting installation of command 
line developer tools.

I tried going along with the installation prompt (on an arm64 and an 
amd64), but the reinstalls didn't fix anything.
