Sure:

# Use lib64 for 64 bit targets, keep the default for the rest.
if test "$libdir" = '${exec_prefix}/lib' ; then

	# We are trying to guess 32-bit target compilation. It's not as easy as
	# it sounds, as there is possible several intermediate combinations.
	ac_config_site_32bit_target=NONE

	# User defined -m32 in CFLAGS or CXXFLAGS:

# Nor FHS nor openSUSE allow prefix/libexec. Let's default to prefix/lib.

libexecdir='${exec_prefix}/lib'

==============================================================================

You can see:
  1. To avoid the libdir variable to be clobbered by this script, it is
     sufficient to pass a --libdir option.
  2. It is not possible to avoid the libexecdir variable modification.
     You can either live with it, or clobber it afterwards.
