I'm not sure it's a bug. The man page of ld clearly states that
-Bstatic, -static, -dn, and -non_shared are equivalent. It's just that
while gcc -Bstatic gets simply passed down to the linker, -static
actually does something and this something makes things work -- I
guess. Also, asking on the CMake mailing list first might might be a
good idea.

No, for the gramcs internal libs there is the BUILD_SHARED_LIBS
option. This is for the external libraries (fftw3, libxml2, etc).
