tools/gpio: Fix build error with musl libc
commitsteinar/wifi_calib_4_9_kernel1696784eb7
upstream. The GPIO tools build fails when using a buildroot toolchain that uses musl as it's C library: arm-broomstick-linux-musleabi-gcc -Wp,-MD,./.gpio-event-mon.o.d \ -Wp,-MT,gpio-event-mon.o -O2 -Wall -g -D_GNU_SOURCE \ -Iinclude -D"BUILD_STR(s)=#s" -c -o gpio-event-mon.o gpio-event-mon.c gpio-event-mon.c:30:6: error: unknown type name ‘u_int32_t’; did you mean ‘uint32_t’? u_int32_t handleflags, ^~~~~~~~~ uint32_t The glibc headers installed on my laptop include sys/types.h in unistd.h, but it appears that musl does not.
