package/linux-tools/perf: add dependency on 32-bit sync builtins
Sync builtins ops are strictly required by perf utility as it uses atomic_xxx() functions. Otherwise building fails like that: |.../output/host/opt/ext-toolchain/bin/../lib/gcc/arc-snps-linux-uclibc/8.2.1/../../../../arc-snps-linux-uclibc/bin/ld: |.../output/build/linux-5.0.7/tools/perf/libperf.a(libperf-in.o): in function `atomic_cmpxchg': |.../output/build/linux-5.0.7/tools/include/asm-generic/atomic-gcc.h:69: undefined reference to `__sync_val_compare_and_swap_4' Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> Cc: Thomas Petazzoni <thomas.petazzoni@bootlin.com> [Thomas: drop Config.in comment] Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> (cherry picked from commit d5edfa6eef6a0e0b124b894be4ce5da4f14c4af7) Signed-off-by: Peter Korsgaard <peter@korsgaard.com>
