Compilation error. -marm not supported

[cliffbry]

On a pi 4 running go1.23.0.linux-armv61.tar.gz kappanhang no longer compiles and generates the error

gcc: errpr: unrecognized command-line option '-marm'

Using google it appears that -marm isn't supported for the compiler gcc version 12.2.0 (Debian 12-2.0-14)

Any pointers to fix this wouldbe appreciated.
