Subject: binutils-cross: Remove exec_prefix from the linker search path

We don't put target libs into a native/cross ${exec_prefix} but having
this in the default search path means all linker scripts have to be relocated.
This is a considerable chunk of files to create multiple copies of for no good
reason.

Instead, patch out the paths we don't need.

+We don't place target libraries within ${exec_prefix}, we'd always place these
+within the target sysroot within the standard library directories. Worse, the
+append_to_lib_path code prefixes these paths with the sysroot which makes even
+less sense.
+
+These directories therefore don't make sense in our case and mean we have to 
+relocate all the linker scripts if they're present. Dropping them 
+gives a reasonable performance improvement/simplification.
