Bug#1073120: FTBS: Compile error on loongarch

[wuruilong]

Source: cubature
Version: 1.0.4+ds-1
Severity: normal
X-Debbugs-Cc: wuruilong at loongson.cn

Dear Maintainer,

Because fftw3 did not add loongarch architecture to generate libfftw3-long3, resulting in a compilation error in this package. loongarch supports long double type, refer to the link: https://loongson.github.io/LoongArch-Documentation/ LoongArch-ELF-ABI-EN.html. 
The link to the fftw3 bug is: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1050691
