Marcel Moolenaar 02409f8cf5 make define2mk.sed work on FreeBSD
In the thread "[1.3.2-rc1] MPC8548CDS/MPC8555CDS configs fails to link",
the define2mk.sed script was identified as the source of the link
failure on FreeBSD. The problem is that sed(1) does not always support
the '+' operator. It isn't on FreeBSD. The attach patch implements the
equivalent, using the '*' operator instead and should work everywhere.

# Sed script to parse CPP macros and generate output usable by make

# It is expected that this script is fed the output of 'gpp -dM'
# which preprocesses the common.h header files and outputs the final
# list of CPP macros (and whitespace is sanitized)

# Only process values prefixed with #define CONFIG_
/^#define CONFIG_[A-Za-z0-9_][A-Za-z0-9_]*/ {
# Strip the #define prefix

# Concatenate string values
s/" *"//g;
