Subject: prereq-build: add additional git detection
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=ab1f3a87063b94f485bd582f32a066b80007bac9;p=openwrt%2Fstaging%2Fsvanheule.git

prereq-build: add additional git detection

With some OS (Guix) the git submodule command is wrapped in
a script. Current logic parse the git submodule script directly.
If it's wrapped the prereq check wrongly fails while 'git submodule
--recursive' is actually available.
Add an additional check that try to directly use the 'git submodule'
command to check if the prereq is satisfied.

Fixes: #9986
