Step back to Debian architectural baseline
libcryptx-perl is build with the compiler flags -sse4.1 and -maes.
SSE4.1 is supported by Intel CPUs, but not by all AMD CPUs. AMD CPUs
support SSE4a, which is not supported by Intel CPUs. The Debian
architectural baseline therefore states:
amd64 x86_64 with no optional extensions (psABI baseline). The
core specification includes MMX, SSE and SSE2 so these
are OK, but SSE3 and up are not guaranteed.
See psABI (Table 3.1: Micro-Architecture Levels) for
amd64 ABI level.
Remove the SSE4.1 and AES compiler flags.
