tpm2-abrmd: allow building without stack smashing protection (SSP)

Browse Source 
Disable SSP if the toolchain does not support it. This must be done
explicitly because configure.ac passes -fstack-protector-all to the
compiler but doesn't contain a link test, so it doesn't detect when
libssp is missing.
