2) alredy answerd ...

answer for question 1)

$> cd mysql55-client && make -V UNIQUENAME
or
$> make -V UNIQUENAME -C /usr/ports/databases/mysql55-client/
 mysql55-client

make.conf entry constructed from UNIQUENAME
 mysql55-client_SET+=	FASTMTX

Please note the '+=' instead '='.
If you have a port where you set more then on option but not as one expression
all ${UNIQUENAME}_SET+= are applied else only the last entry in make.conf.

Additional if you have done `make config' already, then your make.conf entry
is useless since with options NG the OPTIONSFILE has now a higher priority.
