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.
