Flex: use proper m4 binary on target

Flex: use proper m4 binary on target

flex tries to execute:

/data/oe/build/tmp-eglibc/sysroots/x86_64-linux/usr/bin/m4

As workaround you can:

mkdir -p /data/oe/build/tmp-eglibc/sysroots/x86_64-linux/usr/bin/
ln -s /usr/bin/m4 /data/oe/build/tmp-eglibc/sysroots/x86_64-linux/usr/bin/

So this is a bug how OE builds flex.
