[PATCH 4/5] tools: build: fix libiberty feature detection

From: Rabin Vincent
Date: Sun Sep 27 2015 - 14:38:29 EST

Pass CFLAGS and LDFLAGS to the libiberty compile line to make the
detection work when using a cross compiler.

Otherwise perf fails to link even though BFD is detected.

... libbfd: [ on ]

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'
