mpir: fix build on ARM with old binutils versions
Old binutils versions are affected by a bug when the assembly code has
whitespace between [ ] signs, causing a build failure of the mpir
package with ARM toolchains using such old binutils versions.
This commit fixes that by adding a patch that removes those whitespaces.
