Any CFLAGS or LDFLAGS set by the user need to be passed to the feature build command. This many include for example -I or -L to point to libraries and include files in custom paths. In most of the test-*.bin rules in build/feature/Makefile, we use the BUILD macro which always sends in CFLAGS and LDFLAGS. The libiberty build line however doesn't use the BUILD macro and thus needs to send in CFLAGS and LDFLAGS explicitly. Without this, when using custom CFLAGS/LDFLAGS, libiberty fails to be detected and the perf link fails with something like: LINK perf libbfd.a(bfd.o): In function `bfd_errmsg': bfd.c:(.text+0x168): undefined reference to `xstrerror' bbfd.a(opncls.o): In function `_bfd_new_bfd': opncls.c:(.text+0xe8): undefined reference to `objalloc_create' ...
