The issues seem to be that ./configure is setting IFS=' ' without

... oh. I sent my reply before seeing yours.
This is interesting. But then why does
CFLAGS="-O2
-pipe"
./configure
work? I would expect it to fail if IFS was the issue.
It does not. You forgot to export CFLAGS.
+ IFS=' ' read -r k v ldlibs
bash construct ;)

I am unfamiliar with this, can you please explain it?
${VAR//pattern/replacement} replaces every pattern in VAR by replacement. Here
it adds a backslash before every newline.
If I trust https://steinbaugh.com/posts/posix.html#replacement, this is
POSIX-compliant.
