With ubsan enable, libc.so fails to build with:

[...]linkobj/libc_pic.a(setcontext.os): in function `__start_context':
[...]sysdeps/unix/sysv/linux/riscv/setcontext.S:111:(.text+0xc0): relocation
truncated to fit: R_RISCV_JAL against symbol `__GI_exit' defined in .text section
in [...]/linkobj/libc_pic.a(exit.os)

Using 'call' instead of 'j' works regardless whether UBSAN.
