[Bug-edma] Errors building EDMA

[Brandon Invergo]

Hi,

I'm having trouble getting EDMA to build via the GNU Source Release
Collection (I'm the GSRC maintainer).  Note that this is with GCC 4.7.2
and binutils 2.23.1 on Parabola GNU/Linux x86_64. Here's a portion of
the output (it's quite long but repetitive):

It repeats that then for -lm, -lgcc, etc

I interpret it as being a 32-bit vs 64-bit problem. Does EDMA support
32-bit architectures only? If I explicitly set LDFLAGS to include my
/usr/lib32 and directories (I don't know how this is organized on other
distros), there seem to be fewer "skipping incompatible" messages, but
the problem persists:

[build] Build failed. Exiting.  

So it still can't find 32-bit libgcc, though I do have lib32-gcc-libs
installed (the 32-bit GCC libraries on Parabola; I don't know how it's
called on other systems). 

So, I'm not sure how to go about fixing this. Any ideas? Or is EDMA
exclusively 32-bit?

Thanks!
