Subject: build: Define __USE_UNIX98 for old glibc
X-Git-Tag: v1.1.4.1~6
X-Git-Url: https://git.alsa-project.org/?a=commitdiff_plain;h=3cf3fbebddad4e58efbd03e4d2217f0a0d07a2ed;p=alsa-lib.git

build: Define __USE_UNIX98 for old glibc

Otherwise PTHREAD_MUTEX_RECURSIVE isn't defined and we get an error
with old glibc.
