This build failure is the first of its kind, according to autobuild:
http://autobuild.buildroot.net/?reason=zynaddsubfx-3.0.6

Looking at the upstream code, this header inclusion is missing, so the
bug has always been there. My guess is that this "stdint.h" header was
included indirectly from the libc internally. I did not investigated
further. Do you want me to?

Best regards,

Julien.
