Gitea ARM version issue: only for armel

I want try gitea in my arm board. (armv7 arch, kernel 4.9, rootfs: ubuntu 20.04)
But I get the official arm version, found the execute file is armel arch.

XXX$ readelf -h gitea-1.15.6-linux-arm-5

Flags in here: 0x5000200, Version5 EABI, soft-float ABI
this version can’t execute in ubuntu ARM ports system.(Because Ubunut ARM ports support armhf, Flags: 0x5000400(hard-float ABI), or Flags 0x5000002(soft ABI)).

So, could you provided ARMHF binary or help to how to compile the armhf version.
thanks a lot.
