Introduce a Debian build profile to exclude the massive debug package
during build. This was sent the first time as part of a patch series:
<20210411101422.7092-6-bage@linutronix.de>
Most of the patch series is included in the current work on mkdebian
but this is still missing.
A basic test showing better timing.
It is expected that the relative diff will be greater with more symbols:
make tinyconfig
# Enable CONFIG_DEBUG_INFO
time make deb-pkg
real 5m31,104s
user 4m30,960s
sys 0m46,296s
make clean
time make DPKG_FLAGS=--build-profiles=pkg.linux-upstream.nokerneldbg deb-pkg
real 5m28,076s
user 4m25,129s
sys 0m45,489s
Changelog:
v2:
* Align the profile name with the one that ended up in Debian.
v3:
* Prevent the creation of the dbg package when profile is set

Enabling CONFIG_DEBUG_INFO implies building the binary linux-image-*-dbg.
As this increases package build time significantly, one might want to
exclude it from being built.
Add build profile pkg.$sourcename.nokerneldbg for that package
so it can be excluded via e.g.
`make DPKG_FLAGS=--build-profiles=pkg.linux-upstream.nokerneldbg deb-pkg`
The name is the same that is used in Debian's linux package since version
5.17~rc4-1~exp1.

Please ignore v3. Sent the wrong patches.
