Bug#934382: cvxopt: FTBFS on non-amd64 architectures

[Esa Peuha]

Source: cvxopt
Version: 1.2.3+dfsg-1
Severity: serious

As shown by buildd logs [1], compiling src/C/umfpack.c fails on all
architectures except amd64 because umfpack.h is not found. This is
because line 61 of setup.py tests whether any files matching
/usr/lib/x86_64-linux-gnu/libsuitesparse* exist, which is false on
non-amd64 Debian buildds even when libsuitesparse-dev is installed.
