if so, we can just ommit ifeq/endif and add CFLAGS_PIC to
CHECKED_CFLAGS.

the problem is that I don't know what was going on when this happend.
svn annotate command show me that the revision 14531 changed the
portion of the code:

 14531      aldot ifeq ($(strip $(CONFIG_BUILD_LIBBUSYBOX)),y)
 14531      aldot     CFLAGS_PIC:= $(call check_gcc,-fPIC,)
 14531      aldot     LIB_CFLAGS+=$(CFLAGS_PIC)
 14531      aldot endif

but r14531 is:

    r14531 | aldot | 2006-03-14 04:04:00 +0900 (Tue, 14 Mar 2006) | 2 lines

    - revert back to r14406

I've also checked the out put from svn log between 13793 (right before
r14406 for Rules.mak) and 14531 doesn't give me much info. r13638
might be it but i'm not sure.
