This patch breaks the build on Cortex-M4 ARM noMMU configuration:

/home/thomas/projets/buildroot/output/host/bin/arm-linux-gcc -shared -Wl,-elf2flt -static -Wl,--version-script=lib/libi2c.map -Wl,-soname,libi2c.so.0 -o lib/libi2c.so.0.1.0 lib/smbus.o -lc
ld (ld-elf2flt): -shared used without passing a shared library ID

It is trying to unconditionally build a shared library, even when there
is no support for shared libraries.

You can reproduce using the following defconfig:

BR2_arm=y
BR2_cortex_m4=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TOOLCHAIN_EXTERNAL_DOWNLOAD=y
BR2_TOOLCHAIN_EXTERNAL_URL="http://autobuild.buildroot.org/toolchains/tarballs/br-arm-cortex-m4-full-2017.11-rc1.tar.bz2"
BR2_TOOLCHAIN_EXTERNAL_GCC_6=y
BR2_TOOLCHAIN_EXTERNAL_HEADERS_4_13=y
BR2_TOOLCHAIN_EXTERNAL_LOCALE=y
# BR2_TOOLCHAIN_EXTERNAL_HAS_THREADS_DEBUG is not set
# BR2_TOOLCHAIN_EXTERNAL_HAS_THREADS_NPTL is not set
BR2_TOOLCHAIN_EXTERNAL_CXX=y
BR2_INIT_NONE=y
# BR2_PACKAGE_BUSYBOX is not set
BR2_PACKAGE_I2C_TOOLS=y
# BR2_TARGET_ROOTFS_TAR is not set

Could you look into this, and submit an updated version? It would be
preferably to support building without shared library support, because
i2c-tools are very basic, and potentially useful on noMMU systems.

Thanks!

Thomas
