Fix symbol mangling for libjulia-openblas64

Fix symbol mangling for libjulia-openblas64

Forwarded: not-needed
Last-Update: 2020-08-01

when building libjulia-openblas64, we place the lapack shared objects under
lapack64-netlib/ directory. But if exports/gensymbol cannot detect the
existence of the lapack-netlib directory, it will skip the lapack symbol which
results in incomplete symbol mangling (SYMBOLSUFFIX=64_) through objcopy.
