Fixes:
| ../../alsa-utils-1.2.5/alsactl/utils.c: In function 'snd_card_clean_cfgdir':
| ../../alsa-utils-1.2.5/alsactl/utils.c:309:19: error: 'PATH_MAX' undeclared (first use in this function)
|   309 |         char path[PATH_MAX];
|       |                   ^~~~~~~~
| ../../alsa-utils-1.2.5/alsactl/utils.c:309:19: note: each undeclared identifier is reported only once for each function it appears in
