enabling "thumb" option

[AJosephAntony@xxxxxxxxxxxxxx]

Hi,

I was trying to enable the "thumb" option for gcc. I
enabled

MULTILIB_OPTIONS    += mcpu=arm7
MULTILIB_DIRNAMES   += nofmult
MULTILIB_EXCEPTIONS += *mthumb*/*mcpu=arm7*

 in "gcc/config/arm/t-arm-elf" file, configured gcc, installed it. but,
cudnt enable the "-mthumb" option
although gcc seems to work fine. I tried to install gcc-3.4.2. arm-elf-gcc
version 2.95.3 20010315 with
the coldfire patches is also installed.

Thanx
Joe
