This issue was reported by Firas Khalil Khana on a Github pull request

There is no --disable-static in m4. Research in the dark corners of
the Git history has shown that it was apparently added by Peter
Korsgaard back in 2009, in commit
3467cf7305 ("m4: cleanup"). At this
time, the version of m4 used was 1.4.9, but even looking at the
tarball of this old release shows that the ./configure did not support
--disable-static.
So let's drop this option.
