openblas: bump version to v0.2.20

Drop 0001-Complete-support-for-MIPS-n32-ABI.patch as it is now upstream and rebase
0002-Makefile.arm-remove-march-flags.patch.

Also add a hash for the license file.

+Subject: [PATCH] Makefile.arm: remove -march flags
+
+The provided -march flags, especially for ARMv5 and ARMv6 may not
+necessarily match the needed ones: for ARMv5, it might be armv5,
+armv5te, armv5t, etc. If the wrong one is used, the incorrect toolchain
+sysroot can be used in a multilib toolchain.
+
+Therefore, let the user building OpenBLAS pass the appropriate -march
+flag.
+
+The other flags, such as -mfpu=vfp or -mfloat-abi=hard are kept, as they
+are actually required for the build to proceed (OpenBLAS uses VFP
+instructions, and assume an EABIhf ABI).
