| Subject: [PATCH 33/35] gcc: armv4: pass fix-v4bx to linker to support EABI. |
| |
| 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. |
