"Close enough" for the purposes of Buildroot.

Both modules and extensions in either native Lua or as
objects from foreign languages (such as "C") may be 
statically linked into the Lua interpreter.

The process and changes required are well documented,
but would probably be impractical to automate in the
build system.

So the answer for the BR2_PREFER_STATIC_LIB question is:
"Not supported within the Buildroot system."
or on a positive note:
"Buildroot only supports Lua externals as dynamic libraries."
