Unlike libgpiod2, this version of libgpiod relies on the deprecated GPIO
ABI version 1. This ABI used to be enabled by default. However, since
Linux 7.1-rc1 (commit 7673e4c7f7f9 "Do not enable the v1 uAPI by
default"), this is not the case anymore. Failing to enable the ABI
results in a non-functional libgpiod. For instance:
# gpioinfo
gpioinfo: error creating line iterator: Invalid argument
Fix this by enabling the ABI v1 in LIBGPIOD_LINUX_CONFIG_FIXUPS.
