Bug#910045: apertium-hbs-mkd parallel FTBFS

[Helmut Grohne]

Source: apertium-hbs-mkd
Version: 0.1.0~r76450-2
Severity: serious
Tags: ftbfs

apertium-hbs-mkd fails to build from source with sbuild on
unstable/amd64 when DEB_BUILD_OPTIONS is sufficiently parallel. A build
log ends with:

This is a race condition between the "if [ ! -d .deps ]; then mkdir
.deps; fi" commands. When both are executed simultaneously, both see
.deps as absent and try to create it.
