x86: lib: Implement standalone __udivdi3 etc instead of libgcc ones
This patch removes the inclusion of the libgcc math functions and replaces them by functions coded in C, taken from the coreboot project. This makes U-Boot building more independent from the toolchain installed / available on the build system. The code taken from coreboot is authored from Vadim Bendebury <vbendeb@chromium.org> on 2014-11-28 and committed with commit ID e63990ef [libpayload: provide basic 64bit division implementation] (coreboot git repository located here [1]). I modified the code so that its checkpatch clean without any functional changes.
