just checking, that's just a typo right? not expected in config/source at that path?

this

	./gdb/python-config.py

does not exist.

rather

	find . | Grep python-config
		./gdb/python/python-config.py

that, from shell in the env that the build occurs,

	cd src/binutils-gdb
	python3.8 ./gdb/python/python-config.py --ldflags

correctly returns

	-lpython3.8 -lcrypt -lpthread -ldl -lutil -lm -lm -Xlinker -export-dynamic

which should be fine for LDFLAGS

using usual '-L/path' var

	export LDFLAGS="-L/usr/local/pyenv/versions/3.8-dev/lib"
(does this^ need to be rpath'd?  need to poke around in here ...)

	./configure \
	 --prefix=/usr/local/gdb-test \
	 --with-python=/usr/local/pyenv/versions/3.8-dev
	make V=1

_does_ seem to get past the 'python unfound' problem, dropping me into the next issue ... which seems unrelated
