This is also causing macaulay2 to FTBFS in riscv64 [1]:
checking whether the package gfan is installed... gfan:
src/application.cpp:42: char* tail(char*): Assertion `*p==*m' failed.
yes, but < 0.6, will build
...
make -C gfan fetch

error: for the third-party library or program source "gfan"
the source code is not present in the file
"/<<PKGBUILDDIR>>/M2/BUILD/tarfiles/gfan0.6.2.tar.gz"
so either download a "fat" tar file of the Macaulay2 source code
or rerun the Macaulay2 "configure" command with the added option
"--enable-download"
