Subject: trace-cmd: Only add udis86 CFLAGS and LDFLAGS if it is found
Date: Wed, 24 Jul 2019 15:13:49 -0400	[thread overview]
Message-ID: <20190724151349.405d146b@gandalf.local.home> (raw)

[ Patrick, I don't have udis86 on my machines, can you test to see if
  this will include it if you do not set NO_UDIS86? ]

As we need to update both LDFLAGS and CFLAGS, move the test to see if
udisc86 is installed to a variable, and then set NO_UDIS86 if it is not
found. This way we do not need to test if it exists twice, nor have
LDFLAGS set unconditionally.
