Referenced version of 'put' has x86 binaries

[jkeller1ca]

Since the referenced version of 'put' has a few x86 binaries in it (for regression testing), this causes a hiccup in cross-compiling under buildroot. (It checks for proper architecture on your target)

Bump the dependency for 'put' to 0.0.7 to point to a revision that includes no pre-built binaries.
