Commit 37566090 "compiler.h: unify system ifdef cruft here" added both a "#include <errno.h>" and a "extern int errno;" to include/compiler.h which is causing build warnings for some systems, for example for the "netstar" board:
In file included from /home/wd/git/u-boot/work/lib/crc32.c:15: include/compiler.h:28: warning: function declaration isn't a prototype
The declaration of "errno" should be redundant, as <errno.h> is supposed to provide a correct declaration, so drop it.
