fix linking with system libtom

[fperrad]

in all case, we want link with 'libtomcrypt' and 'libtommath' (in this sequence).

in bundled case, just add the specific location of these libraries

I think 7ab8f61 sorts this out a different way? Let me know if I'm missing something. Thanks.

sorry, still failing (tested with Buildroot, see https://github.com/fperrad/br/commits/libtom)

-ltomcrypt must been always before -ltommath

Did you regenerate the configure script after patching configure.ac ?

[fperrad]

You are right. I missed the DROPBEAR_AUTORECONF = YES in Buildroot.
The issue is fixed.
