Fixes build against uClibc. uClibc provides 2 versions of clock_gettime(), one with realtime support and one without (this is so you can avoid linking in -lrt unless actually needed). This means that the clock_gettime() don't need -lrt. We still need it for timer_create() so we check for this function in addition. We also need check if -lm is needed for isnan(). Both -lm and -lrt are needed for libs_qga. Signed-off-by: Natanael Copa <ncopa@alpinelinux.org> --- Changes v3->v4: - Use $pthread_lib from previous pthread test We don't need to add it to $LIBS since it should be there already configure | 36 ++++++++++++++++++++++++++++++++++-- 1 file changed, 34 insertions(+), 2 deletions(-)
