[ruby/rubygems] Add `MAKEFLAGS=-j` by default before compiling:
- Depending on the native extension, it can greatly reduce compilation
time when executing recipes simultaneously.
For example on Prism:
```
# Before
time gem install prism
Building native extensions. This could take a while...
Successfully installed prism-1.6.0
1 gem installed
gem install prism 3.61s user 0.80s system 95% cpu 4.595 total
```
```
# After
time MAKEFLAGS="-j" gem install prism
Building native extensions. This could take a while...
Successfully installed prism-1.6.0
1 gem installed
MAKEFLAGS="-j" gem install prism 4.47s user 1.27s system 246% cpu 2.330 total
```
I don't think adding `-j` as a default is harmful, but I'm admitedly
not very knowledgable when it comes to compiler.
