Build fails on Fedora Rawhide ppc64le

I maintain the golang-modernc-sqlite package on Fedora. Building version 1.34.4 of the package on Rawhide fails with this error on ppc64le:

modernc.org/sqlite/vfs
# modernc.org/sqlite/vfs [modernc.org/sqlite/vfs.test]
./vfs_linux_ppc64le.go:1327:44: cannot use uint32(294) (constant 294 of type uint32) as int32 value in argument to libc.X__assert_fail
FAIL	modernc.org/sqlite/vfs [build failed]

The build works fine on Rawhide aarch64 and x86_64. The build worked fine on all architectures on Fedora 41.
