Subject: Remove timestamp issues caused by the compilation of dftables external
X-Git-Tag: Release-2010-05/1~9453^2~4130
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fa09bf15aa200c6baed97dd4fd1b9384250eb0b4;p=openembedded.git

Remove timestamp issues caused by the compilation of dftables external
to the makefile (doesn't work when using ccache on a fast system because
it attempts to rebuild dftables within the makefile).  The change fixes
the original problem that dftables was compiled by default with the target
compiler.
