Subject: [PATCH] Build system: under Linux, do not try to statically link
libgomp even with -Dprefer_static=true
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
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
