Build system: under Linux, do not try to statically link libgomp even with -Dprefer_static=true 

Under Debian 12, it fails with:
/usr/bin/ld: /usr/lib/gcc/x86_64-linux-gnu/12/libgomp.a(team.o): réadressage R_X86_64_TPOFF32 vers symbole caché « gomp_tls_data » ne peut pas être utilisé en créant un objet partagé
