#10542: configure incorrectly detects VIA c3 and enables cmov etc...

 Reporter:  andrew@…           |           Type:  Bug Report - General
   Status:  new                |       Priority:  minor
Milestone:  0.24.3             |      Component:  MythTV - General
  Version:  0.24.2             |       Severity:  medium
 Keywords:  c3 cmov configure  |  Ticket locked:  0
-------------------------------+--------------------------------------
 On gentoo using the media-tv/mythtv-0.24.2_p20120315 ebuild ./configure
 uses --enable-proc-opt which incorrectly assumes that my Ezra CPU has cmov
 extensions etc...
 When it has compiled the binary crashes with 'illegal instruction' trying
 to run mythtv-setup

 Attempting to work around this by passing --tune=c3 --arch=i586 --enable-
 mmx --enable-amd3dnow --enable-memalign-hack --disable-sse --disable-ssse3
 --disable-amd3dnowext --cpu=c3 etc....

 Seems this bug appeared 5 years ago and was squashed - but it seems to
 have come back.
