haproxy relies on linking the binary using gcc, so there is no real need to
hardcode both (CC and LD). Setting 'LD = $(CC)' will make the build system
a bit more cross-compile friendly because only the right cross-compiler has
to be passed via make.
#### Toolchain options.
# GCC is normally used both for compiling and linking.
CC = gcc
-LD = gcc
+LD = $(CC)
#### Debug flags (typically "-g").
# Those flags only feed CFLAGS so it is not mandatory to use this form.
