Put BIGNUM=no at the right place, where there is no libgmp.

This change doesn't appear to be related and seems to increase code duplication. What's its purpose?

What the toolchain file does is basically 2 things:

  1. Setting the -m32 flag
  2. Redirecting the library/header search path to the static dependencies (depends dir)

Since secp256k1 has no depends the second point makes no sense, and would prevent cmake from finding libgmp:i386 on the OS file system. Simply adding the -m32 flag is enough and solves the issue.
