Hello,

This isn’t really the best solution I would say, but it will at least work for now.

I suppose there is an issue in the perl build system and that either the -fstack-protector-all flag is being filtered or it links libc in a funny way.

I would propose to make this conditional to i586 because the module builds fine on all other architectures.

P.S. Did you try adding -lssp to the linker flags?
