[OS X TeX] universal-darwin bin dir

[jfbu]

Hi,

I have MacTeX 2014 on Mac OS X Mavericks (latest)

I observed today that /usr/local/texlive/2014/bin
contains both of 

universal-darwin

and 

x86_64-darwin

this is on a MBA, hence x86_64, thus the latter is the
directory /usr/texbin points to.

universal-darwin weighs 176M and I feel very much like doing
rm -fr on it.

Is there any reason I should not?
