Reverting this change in Dizzy based build fixes the signatures for
gcc-cross(-initial)-arm
for gdb-cross-arm, there is still datadir -> TUNE_PKGARCH dependency from even
older change:
OE qemuarm7@ ~/build/oe-core/openembedded-core $ git show -1 3e87aba1
commit 3e87aba1ee2ca0e39ba66fb7cba52e48df499c23
Author: Phil Blundell <p...@pbcl.net>
Date: Wed Apr 24 16:15:54 2013 +0100
gdb-cross: Adjust ${datadir} to avoid file conflicts in sysroot
+datadir .= "/gdb-${TUNE_PKGARCH}${TARGET_VENDOR}-${TARGET_OS}"
Reverting this change fixes gdb-cross-arm signatures.
Will try what happens when I revert this in master and move --with-arch
options to gcc-target.inc only.
