Subject: [PATCH] linux: workaround ld wrapper issue

The ld wrapper leads to the following linking error on x86_64, when
building pkgsLLVM.linux_latest:

x86_64-unknown-linux-gnu-ld: error: ../arch/x86/boot/setup.ld:15: unable to move location counter (0x204) backward to 0x1ef for section '.bstext'
