[PATCH] blackfin: Makefile: Skip reloc overflow issue when COMPILE_TEST enabled

From: Chen Gang
Date: Wed Apr 08 2015 - 17:05:36 EST


l1_text is at L1_CODE_START (e.g. for bf533, 0xff800000). If the kernel
is too big, it may be overwritten, the related issue:

LD init/built-in.o
init/built-in.o: In function `do_early_param':
init/main.c:(.init.text+0xe0): relocation truncated to fit: R_BFIN_PCREL24 against symbol `strcmp' defined in .l1.text section in arch/blackfin/lib/lib.a(strcmp.o)
init/main.c:(.init.text+0x10e): relocation truncated to fit: R_BFIN_PCREL24 against symbol `strcmp' defined in .l1.text section in arch/blackfin/lib/lib.a(strcmp.o)
init/built-in.o: In function `unknown_bootoption':

blackfin is for embedded system, the size limitation is acceptable, so
it is not the real world issue, which should be skipped if COMPILE_TEST
enabled.
