Dear williams, This patch is for support static building using cross-compiler for embedded targetboard like ARM. When we use -static option for static binary on embedded board after patch. I tested various toolchain.(e.g: codesourcery toolchain , my self toolchain , cross-tool project's toolchain) Ref) Don't forget "-static" configuration(CFLAGS += -O2 -static) in Makefile When you need static linking.
