As I see it there are two problems in the package:
1. Hardening rules are not properly passed to the build system, for that you
might need to set CFLAGS and LDFLAGS as:
make -C src CFLAGS="$(CFLAGS)" LDFLAGS="$(LDFLAGS)" OS=Linux
CPU=$(DEB_HOST_ARCH_CPU) picolisp tools gate
make -C src64 CFLAGS="$(CFLAGS)" LDFLAGS="$(LDFLAGS)" OS=Linux
This way the build system takes the flags, but FTBFS, with full hardening set.
2. amd64 and armhf arches fail because the linkage is trying to link non-PIE
object code.
The following patch should fix the issue with -fPIE, but you are still not
passing hardening flags to the build.
I have not been able to test on armhf, but once I do, and if you dont have
inconvenient I shall proceed with a NMU.
