When building a target application with static linking mode via
makefiles and enable linking to ibverbs libs by setting
"CONFIG_RTE_IBVERBS_LINK_STATIC=y". The libibverbs.pc will be
chosen and all the libs listed in the file will be linked
by default. Some static lib archives may contain the same files
and common interfaces inside.
The "--no-whole-archive" needs to be enabled for the linker to
discard the useless symbols and resolve the symbols redefinition
error.
