With a C library which does not provide fenv.h, it won't work at runtime: Crash after an "import numpy" on python. Since numpy v1.16.0: "Alpine Linux (and other musl c library distros) support We now default to use fenv.h for floating point status error reporting. Previously we had a broken default that sometimes would not report underflow, overflow, and invalid floating point operations. Now we can support non-glibc distrubutions like Alpine Linux as long as they ship fenv.h." Disable python-numpy for uClibc to avoid the runtime errors. ARC's glibc used to have an incomplete fenv.h, but this has been fixed since commitbe0aaaaecd("toolchain: bump ARC tools to arc-2019.03 release"), so we don't need an exception for ARC. Two patches attempted to fix the build for uclibc and glibc for ARC, but didn't fix the runtime issue. Remove those patches.

NumPy is the fundamental package for scientific computing
|
|
with Python.
|
|
|
|
Note that NumPy needs fenv.h fully supported by the
|
|
C library.
