[easybuild] About python extension build

[Yoshihito Horigome]

Hello, all

I attempted to build python using Python-2.7.11-foss-2016a.eb, 

but several extensions are introduced at the same time in this eb file.

Among them, scipy is introduced, but I do not know where the fortran option is specified at this time.

Because the verification environment is aarch64, but the fortran option x86_64 is called. 

Although the flow to the following files could be read, the place where the option was specified is unknown.

$ cat /etc/redhat-release
CentOS Linux release 7.3.1611 (AltArch)

$ uname -a
Linux scw-d80f87 4.9.23-std-1 #1 SMP Mon Apr 24 13:18:14 UTC 2017 aarch64 aarch64 aarch64 GNU/Linux
