build error with benchmark-node-micro-benchmarks CI job

[mscdex]

"make[1]: execvp: printf: Argument list too long" when building SSL?

Here is the benchmark job console output.

A few questions:

1. did you select a specific set of tests to run?
2. do you know if this is a recent issue?

@uttampawar is this something you might be able to help look at?

FTR, this is a part of the error:

I was looking into this, and it seems that because the build directory is long

/home/iojs/build/workspace/benchmark-node-micro-benchmarks/benchmarking/experimental/benchmarks/community-benchmark/node/

when make needs to create the command line to link all the obj files, and it uses absolute paths, the result is vvveeerrrryyyy long.

tl;dr it now builds both binaries. Actual benchmarks "should" work.
