Just to understand what you are trying to do:

Would like to have both .a and .so files for your library in your SDK?

What should be on the rootfs? I guess the .so

You can check the contents of your packages with:

oe-pkgdata-util list-pkg-files -p <package-name>

How do you build your stuff? autotools?

I needed to do the following in my recipe with autotools:

# By default EXTRA_OECONF is set to --disable-static ...
# Let's get rid of this
DISABLE_STATIC = ""
EXTRA_OECONF := "${@oe_filter_out('--disable-static', '${EXTRA_OECONF}', 
d)}"
# enable static and disable shared (for fun)
EXTRA_OECONF += "--enable-static --enable-shared"

I added this to local.conf:

# -->
IMAGE_INSTALL_append = " libhw-so-a"
# add libhw-so-a-dev and libhw-so-a-staticdev to SDK:
TOOLCHAIN_TARGET_TASK_append = " libhw-so-a-staticdev libhw-so-a-dev"
# <--

That's the content of the packages produced:

libhw-so-a:
         /usr/lib/libhw.so.0
         /usr/lib/libhw.so.0.0.0
libhw-so-a-dbg:
         /usr/lib/debug/usr/lib/libhw.so.0.0.0.debug
         /usr/src/debug/libhw-so-a/1.0-r0/libhw-so-a-1.0/lib/lib_hw1.c
         /usr/src/debug/libhw-so-a/1.0-r0/libhw-so-a-1.0/lib/lib_hw2.c
libhw-so-a-dev:
         /usr/include/lib_hw.h
         /usr/lib/libhw.so
libhw-so-a-staticdev:
         /usr/lib/libhw.a

in the rootfs:

./usr/lib/libhw.so.0
./usr/lib/libhw.so.0.0.0

in the SDK:

./opt/poky/2.4/sysroots/armv7a-neon-poky-linux-gnueabi/usr/lib/libhw.so
./opt/poky/2.4/sysroots/armv7a-neon-poky-linux-gnueabi/usr/lib/libhw.a
./opt/poky/2.4/sysroots/armv7a-neon-poky-linux-gnueabi/usr/lib/libhw.so.0
./opt/poky/2.4/sysroots/armv7a-neon-poky-linux-gnueabi/usr/lib/libhw.so.0.0.0
./opt/poky/2.4/sysroots/armv7a-neon-poky-linux-gnueabi/usr/include/lib_hw.h

Can you cook up an example where we can see/reproduce your problem?
