multilib issues

[Adrian von Bidder]

Heyho!

For doing some experiments (on ARM, but this shouldn't matter) I set up
the t-arm-elf file to include these:

MULTILIB_OPTIONS     = marm/mthumb
MULTILIB_DIRNAMES    = arm thumb
MULTILIB_EXCEPTIONS  =

MULTILIB_OPTIONS     += fno-pic/fpic
MULTILIB_DIRNAMES    += static pic
MULTILIB_EXCEPTIONS  +=

MULTILIB_OPTIONS     += mno-single-pic-base/msingle-pic-base
MULTILIB_DIRNAMES    += multipic singlepic
MULTILIB_EXCEPTIONS  += fno-pic/msingle-pic-base

(and set up MULTILIB_DEFAULTS according. But that works ok).

So I should get
.;
thumb;@mthumb
pic;@fpic
pic/singlepic;@fpic@msingle-pic-base
thumb/pic;@mthumb@fpic
thumb/pic/singlepic;@mthumb@fpic@msingle-pic-base

But the MUTILIB_EXCEPTIONS does not seem to be working, as I get
additionally:
singlepic;@msingle-pic-base
thumb/singlepic;@mthumb@msingle-pic-base

Any comments? Where did I misunderstand MULTILIB_EXCEPTIONS (or is there
a bug?)

[gcc-3.0.3, host=i686-linux, btw]
