[uClibc] [help] missing dirs in *-linux-uclibc-gcc default search list

[ZHUANGYUYAO]

Hi,

I just compiled gcc-3.3.4 using the latest buildroot cvs update 
(ARCH=i386), the compilation finished successfully, but I noticed that 
library-path $(STAGING_DIR)/usr/lib:$(STAGING_DIR)/usr/local/lib and 
include-path $(TAGING_DIR)/usr/include:$(STAGING_DIR)/usr/local/include 
no longer exist  in  $(ARCH)-linux-uclibc-gcc's default search-dir list.

some of my source code failed to compile, the compiler complains that 
some header files are missed. Adding -L and -I to Makefiles needs huge 
work, I just want to find a way to put the dirs back into the default 
search list.

I'v searched google but found nothing helpful. Could anyone help me to 
solve such a problem?

Thanks very much!
