+The LINK_SPEC for linux gets overwritten by linux-eabi.h which
+means the value of TARGET_FIX_V4BX_SPEC gets lost and as a result
+the option is not passed to linker when chosing march=armv4
+This patch redefines this in linux-eabi.h and reinserts it
+for eabi defaulting toolchains.
+
+We might want to send it upstream
