Message:

mips64el: binutils: Rewrite the explanation of --enable-default-hash-style=gnu

On MIPS there are some differences in the classic ELF hash table vs.
GNU-style hash table decision.

-          <para>By default, the linker would generate both the GNU-style

+          <para>By default, the linker would generate the classic ELF hash
+          table for shared libraries and dynamically linked executables
+          because the GNU-style hash table is incompatible with the MIPS o32

+          Glibc package) supports the GNU-style hash table, and this LFS
+          edition does not support the o32 ABI.  So this is used to make the
+          linker generate the GNU-style hash table instead of the classic
+          ELF hash table by default, as the GNU-style hash table is faster
