Bug#737031: [saga] SAGA rebuilds without LAS support

[Graham Inggs]

Package: saga
Version: 2.1.0+dfsg-1+b2
Severity: normal

Saga was recently rebuilt against liblas2, but because of changes in 
liblas 1.70 the test in configure.in below fails.
AC_CHECK_LIB([las], [LAS_GetVersion], LASFOUND=1,,)

The line below appears in the build logs, and saga does not get linked 
against liblas2 or liblas-c2.
checking for LAS_GetVersion in -llas... no
