Required by libstdc++.so.6

[huangwei2013]

Found Error：
libstdc++.so.6: version CXXABI_1.3.8

I got libstdc++.so.6 but do not support CXXABI_1.3.8, as below
`CXXABI_1.3

CXXABI_1.3.1
CXXABI_1.3.2
CXXABI_1.3.3
CXXABI_1.3.4
CXXABI_1.3.5
CXXABI_1.3.6
CXXABI_1.3.7
CXXABI_TM_1
`

when try the base example：

 from interpret.glassbox import ExplainableBoostingClassifier
 ebm = ExplainableBoostingClassifier()
 ebm.fit(X_train, y_train)

My Server:
Centos7.5 ( Aliyun, Qcloud both tried)
gcc/g++ 4.8.5
libstdc++.so.6.0.19

Solution：
Copy from somewhere a libstdc++.so.6.0.24 , an make a sofelink of libstdc++.so.6

Of course it‘s not problem of interpretML，but still a trouble for newbe .

Hi huangwei2013,

Thanks for reporting this to us! We were able to remove the dependency on libstdc++ by statically linking it in, which should remove this class of problem for you and anyone else with older versions of that library. The change has been pushed to the develop branch. We'll be putting out a release in the next day or two that will merge it into master and to pypi.

This now in master and on pypi.
