hi.

if filedate of gnu/dist/toolchain/binutils/arlex.l is older than
gnu/dist/toolchain/binutils/arlex.c, make build will fail
with following messages.

> /bin/sh /usr/src/tools/toolchain/../../gnu/dist/toolchain/binutils/../ylwrap "true" /usr/src/tools/toolchain/../../gnu/dist/toolchain/binutils/arlex.l lex.yy.c /usr/src/tools/toolchain/../../gnu/dist/toolchain/binutils/arlex.c --  
*** Error code 1

it's because ylwrap checks if lex.yy.c is exist or not.
