# Find a program when cross-compiling, or use a default when not.
# RESULT = variable which records the outcome
# CROSS_PROG = program to look for when cross-compiling
# NORMAL_PROG = program to use when not cross-compiling
# Example: KPSE_CROSS_PATH_PROG([TANGLE], [tangle], [./tangle]) sets
# 'TANGLE' to the program 'tangle' found in PATH when cross-compiling,
# and to './tangle' if not.
