Bug#998377: mlv: FTBFS with new dash version due to bashism in configure.ac

[Johannes Schauer Marin Rodrigues]

Source: mlv
Version: 3.1.0-6
Severity: serious
Tags: ftbfs
Justification: fails to build from source (but built successfully in the past)

Hi,

since the upload of dash 0.5.11+git20210903+057cd650a4ed-2 yesterday,
mlv FTBFS with:

./configure: 8146: test: xFrench: unexpected operator
./configure: 8146: test: xEnglish: unexpected operator
./configure: 8146: test: xSpanish: unexpected operator
configure: error: Unknown or unsupported Language "French".  Only "French 
English Spanish" are supported in this version of this library.

The reason is a bashism in configure.ac. The attached patch fixes the problem.

Thanks!

cheers, josch
