Bug#890384: ignition-math4: baseline violation on amd64

[Adrian Bunk]

Source: ignition-math4
Version: 4.0.0+dfsg1-1
Severity: serious

ifeq ($(DEB_HOST_ARCH),amd64)
SSE_FLAGS = -mfpmath=sse -msse -msse2 -msse3 -mssse3 -DSSE
endif

SSE3 and SSSE3 are not part of the amd64 baseline.

"-mfpmath=sse -msse -msse2" are already enabled
by default on amd64, no need to do that manually.

The SSE define does not seem to be used anywhere in the code.
