commit 6e4b4f0eca88e47def703f90a403fef5b96730d5 upstream. When building with clang the toolchain refuses to link the signals testcases since the assembly code has a reference to current which has no initialiser so is placed in the BSS: /tmp/signals-af2042.o: in function `fake_sigreturn': <unknown>:51:(.text+0x40): relocation truncated to fit: R_AARCH64_LD_PREL_LO19 against symbol `current' defined in .bss section in /tmp/test_signals-ec1160.o Since the first statement in main() initialises current we may as well fix this by moving the initialisation to build time so the variable doesn't end up in the BSS.
