Do you have "build-essential" installed on the host system, assuming it's Debian-based?

That version of GCC looks a bit old. I'm not sure whether it's recent enough for
OpenJDK 14.

FWIW, I'm using a different approach for cross-building OpenJDK which works particularly
easy on Debian and Ubuntu due to Multi-Arch support which allows co-installing library
packages for different architectures on one system.

I have documented it here: https://wiki.debian.org/PortsDocs/BootstrappingOpenJDK
