This patch enables building binutils using TCC and Mes C Library
* disable building DOC
* remove signed int trickery that does not work with TCC
* fixe the malloc prototype to use size_t
* add missing includes
* remove C99'isms to avoid of mixing code and variable declaration
* [MES_BOOTSTRAP]: remove strncmp to avoid duplicat symbol
