There are at least two ways to sed CFLAGS/LDFLAGS cor 'configure'. Set
then in your environment or create a

 [install-prefix]/etc/config.site file

like this one for an UltraSPARC:

# /etc/config.site
CC="gcc -mcpu=ultrasparc -mtune=ultrasparc -m64"
[...]
CFLAGS="-O3"
[...]
LDFLAGS="-64 -L/opt/gnu/lib [...]"

Your compiler manpage will tell you which ones to use.
In case you have 64-bit-only platform like DEC Alpha I assume the
compiler will create 64 bit binaries without being explicitly told to
do so,
 I forgot another option which is valid with MIPSPro on IRIX. There is a
 
 /etc/compiler.defaults
 
 file which could look like this:
 
 sirius: 9:01:25 ~> cat /etc/compiler.defaults
 -DEFAULT:abi=64:isa=mips4:proc=r10k
 
 Note that, while the N64 ABI is simply called '64', you have to put
 'n32' for the N32 ABI (to differenciate from 'o32'),
