Currently due to the occurrence of 6 arguments from
`gen-ldflags.go` leads to a bug where the binaries
genenerated have wrong names.
As shown below.

This PR fixes this issue by retaining the previous release
binary names.

Update the check_minimum_version function to use numeric comparison (not
string comparison) on components of version numbers. Fixes the following
output:
```
$ make
Checking deps:
ERROR
OSX version '10.11.6' not supported.
Minimum supported version: 10.8
make: *** [checks] Error 1
```
Golang 1.6 is default version for the build now.
Additionally set 'GODEBUG=cgocheck=0' for now, until
we fix the erasure coding package.

- over the course of a project history every maintainer needs to update
its dependency packages, the problem essentially with godep is manipulating
GOPATH - this manipulation leads to static objects created at different locations
which end up conflicting with the overall functionality of golang.
This also leads to broken builds. There is no easier way out of this other than
asking developers to do 'godep restore' all the time. Which perhaps as a practice
doesn't sound like a clean solution. On the other hand 'godep restore' has its own
set of problems.
- govendor is a right tool but a stop gap tool until we wait for golangs official
1.5 version which fixes this vendoring issue once and for all.
- govendor provides consistency in terms of how import paths should be handled unlike
manipulation GOPATH.
This has advantages
- no more compiled objects being referenced in GOPATH and build time GOPATH
manging which leads to conflicts.
- proper import paths referencing the exact package a project is dependent on.
govendor is simple and provides the minimal necessary tooling to achieve this.
For now this is the right solution.
