Re: git: f05f6dcedb5d - main - comms/gqrx: Turn off ASLR

Hello Ganael,

I didn't know that were a way to disabling aslr in a port! This is really
nice.

I'm having a lot of segfaults and tab crashing on firefox @aarch64 and
mikael@ sugested turning it off to see if it fixes.
I will test first with sysctl aslr off and if it works I will test port
option.

So syntax is:

USES+= elfctl
ELF_FEATURES= +noasr:<path_to_something>?

Thanks,
