I read the printings like you and I am confused.
let's take valgrind as example:
1.) the rootfs build goes to:
/poky/build/tmp/work/cortexa5hf-vfp-poky-linux-gnueabi/valgrind/3.11.0-r0/deploy-debs/cortexa5hf-vfp/valgrind_3.11.0-r0_armhf.deb
the extension of the deb package say it its hard float.
2.) I transfer it to my device
3.) console at the evalboard
#############
root at sama5d3xek:/tmp# dpkg -r valgrind
(Reading database ... 14780 files and directories currently installed.)
Removing valgrind:armhf (3.11.0-r0) ...
root at sama5d3xek:/tmp# dpkg -i valgrind_3.11.0-r0_armhf.deb
dpkg: error processing archive valgrind_3.11.0-r0_armhf.deb (--install):
package architecture (armhf) does not match system (armel)
Errors were encountered while processing:
valgrind_3.11.0-r0_armhf.deb
root at sama5d3xek:/tmp#
#############
I got the information from here(hope it works):
https://books.google.de/books?id=yNi6BwAAQBAJ&pg=PA148&lpg=PA148&dq=yocto+set+floating+point&source=bl&ots=HXh65nWpHc&sig=4UElzv4dz70xECsqw5lnCYuUZiI&hl=de&sa=X&ved=0ahUKEwjOhrib2KnOAhVB1RQKHbXkAPAQ6AEIQDAE#v=onepage&q=yocto%20set%20floating%20point&f=false
Maybe the deb generation has a bug?

here it is marking that your build is using hard-float. are you running
image from same build on the target ? or is it some prebuilt image that
you are trying to add on to ?
