Builds for me on x86_64.

How much does this add to the size of the lapack package?  Would we want 
to install the libraries and headers into another output?  IFAIK, not 
many codes make use of both the standard interface and LAPACKE at the 
same time.

Before:

store item                                                       total    self
/gnu/store/dkz7fips64c5h05hfg6lmvhmb7jlipb6-lapack-3.5.0
71.4     6.4   9.0%
/gnu/store/gaximh48qbqf4712bw224ghq919hqp64-gfortran-4.9.3-lib
64.9    27.1  38.0%
/gnu/store/8m00x5x8ykmar27s9248cmhnkdb2n54a-glibc-2.22
37.9    36.5  51.1%
/gnu/store/5y72ql4zbnbd50lf88k91k0y766kq75x-bash-static-4.3.42
1.4     1.4   2.0%
total: 71.4 MiB

After:

store item                                                       total    self
/gnu/store/1whq33kw6136h4jcy14cfk1klx5hn1s3-lapack-3.5.0
97.2     9.4   9.6%
/gnu/store/gaximh48qbqf4712bw224ghq919hqp64-gfortran-4.9.3-lib
64.9    27.1  27.9%
/gnu/store/v39bh3ln3ncnzhyw0kd12d46kww9747v-gcc-4.9.3-lib
60.7    22.9  23.5%
/gnu/store/8m00x5x8ykmar27s9248cmhnkdb2n54a-glibc-2.22
37.9    36.5  37.5%
/gnu/store/5y72ql4zbnbd50lf88k91k0y766kq75x-bash-static-4.3.42
1.4     1.4   1.4%
total: 97.2 MiB

Basically, closure size goes up by 20MiB, but the store item itself is
only 3MiB bigger.

WDYT?
