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

(...)

Find it:

# Change an ELF binary's feature control note
#
# Feature:      elfctl
# Usage:        USES=elfctl
# Valid ARGS:   none
#
# Variables
#
#   ELF_FEATURES=       featurelist:path/to/file1 \
#                       featurelist:path/to/file1 \
                        featurelist:path/to/file2
#
# The file paths listed in ELF_FEATURES are relative to ${BUILD_WRKSRC}.
#

Nice!
