Source packages need to be checked, that they behave in the same way as for the i386 architecture; the packaging has to be checked for things like:

ifeq ($(DEB_HOST_ARCH),i386)
  ...
endif

ifeq ($(filter $(DEB_HOST_GNU_CPU),alpha i486 hppa ia64 powerpc s390 sparc x86_64),)
  ...
endif

have to be changed into

ifneq (,$(filter $(DEB_HOST_ARCH),i386 lpia))
  ...
endif

ifeq ($(filter $(DEB_HOST_GNU_CPU),alpha i486 i686 hppa ia64 powerpc s390 sparc x86_64),)
  ...
endif

Things to watch:

• debian/control: Architecture attribute. Explicit use of i386', add lpia'. Look at the rules file.

• DEB_XXX_ARCH is lpia' instead of i386'.

• DEB_XXX_GNU_CPU is i686' instead of i486', but better use DEB_XXX_ARCH.

• Use of uname

• Use of preprocessor in dpatch
• Use of linux-gnu to influence package behaviour, we're linux-gnulp, use of DEB_XXX_GNU_OS, comparing with `linux-gnu'
• inclusion of architecture specific files (include debian/vars.$(DEB_XXX_ARCH), make Debian-i686)
• building optimized libraries (i686); only one is built for lpia using the default values.
• explicit setting of compiler options -march / -mtune. The defaults should be taken.
