# Find a program when cross-compiling, or use a default when not.
# $1 = variable which records the outcome
# $2 = program to look for when cross-compiling
# $3 = program to use when not cross-compiling


# Set BUILD$1 to $2 when cross-compiling, to $($1) if not.
# Example: KPSE_CROSS_BUILD_VAR([CC], [cc]) sets 'BUILDCC' to 'cc'
# if cross-compiling, and to '$(CC)' if not.
