4Subject: [PATCH] gcc: armv4: pass fix-v4bx to linker to support EABI.
5
6The LINK_SPEC for linux gets overwritten by linux-eabi.h which
7means the value of TARGET_FIX_V4BX_SPEC gets lost and as a result
8the option is not passed to linker when chosing march=armv4
9This patch redefines this in linux-eabi.h and reinserts it
10for eabi defaulting toolchains.
11
12We might want to send it upstream.
