Since Buildroot commit [1] "update to Bootlin toolchains 2025.08-1", the TestXvisor fails when building xvisor with gcc 15.1.0. Since xvisor is now fixed, opensbi 1.5 fail to build with gcc-15 for the same reasons. opensbi 1.6 include a fix for C23 enabled compilers [2] [1]947dbc92a2[2]d539d64a23Cc: Julien Olivain <ju.o@free.fr> Signed-off-by: Romain Naour <romain.naour@smile.fr> Signed-off-by: Julien Olivain <ju.o@free.fr>
