lishdata-stress compilation failure when TARGET_FORCE_STATIC set

[hcodina]

Hi,

libshdata-stress fails to compile when TARGET_FORCE_STATIC is set.

Using:
export ALCHEMY_HOME=$(pwd)/alchemy
export ALCHEMY_TARGET_OUT=$(pwd)/out
ALCHEMY_WORKSPACE_DIR=$(pwd) TARGET_FORCE_STATIC=1 ${ALCHEMY_HOME}/scripts/alchemake V=1 libulog libfutils libshdata libshdata-stress

Lead to the following results:

It seems that the issue is that libshdata-section-lookup.a reference a symbol present in libshdata.a.
In the link command line, the order used for .a files is libshdata.a then libshdata-section-lookup.a.
As the symbol is not used by libshdata.a itself or by the obj files, the linker discards the symbol before parsing ibshdata-section-lookup.a.
