Make.rules fails to generate cap_names.h and af_names.h

This is kind of a weird one.

I'm from Solus and we are in the middle of our Python 3.7 upgrade and happened upon a bizarre bug while rebuilding AppArmor. The current Make.rules escapes # when calling out to shell to populate the CAPABILITIES and AF_NAMES variables used to generate cap_names.h and af_names.h. If I remove the escape (\# --> #) everything builds correctly.

See: rules.patch

Relevant software versions:

• AppArmor 2.13.3
• Bash 5.0.11
• gcc 9.2.0
• Make 4.3
• sed 4.8
