- Previously these variables were marked as "precious" only in LALApps.
  In particular the value of LALSUITE_BUILD was lost when re-configuring
  any of the LAL libraries, which caused the re-configuring to fail.
- Defines a new macro LALSUITE_ARG_VAR in lalsuite_build.m4 which declared
  LALSUITE_BUILD and LALSUITE_TOP_SRCDIR "precious", can be used to add
  other variables in future.
- LALSUITE_ARG_VAR now called at the start of every ./configure.ac, apart
  from the top-level one.
