[Buildroot] [PATCH] support/dependencies/dependencies.sh: awk is needed by Buildroot

[Thomas Petazzoni]

A basic Fedora 42 container does not have 'awk' installed, but it is
needed by Buildroot. First by check-host-python3.sh:

support/dependencies/check-host-python3.sh: line 6: awk: command not found
support/dependencies/check-host-python3.sh: line 19: awk: command not found
support/dependencies/check-host-python3.sh: line 19: awk: command not found

but then even building host-expat assumes awk is available:

config.status: creating Makefile
./config.status: line 1404: awk: command not found
config.status: creating expat.pc
./config.status: line 1404: awk: command not found

Since it's a pretty basic tool, make it part of the tools checked by
dependencies.sh. One minor annoyance is that check-host-python3.sh is
executed *before* dependencies.sh does its thing, so when 'awk' is not
available, we end up seeing:

support/dependencies/check-host-python3.sh: line 6: awk: command not found
support/dependencies/check-host-python3.sh: line 19: awk: command not found
support/dependencies/check-host-python3.sh: line 19: awk: command not found
which: no awk in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin)
You must install 'awk' on your build machine
make: *** [support/dependencies/dependencies.mk:27: dependencies] Error 1

It would be nice to have the awk check *before* it gets used in
check-host-python3.sh, but that's a topic for another patch.
