Subject: The bsd_signal declaration shouldn't be visible if API > 21.
X-Git-Tag: android-x86-9.0-r1~66^2~214^2~63^2~29^2~52^2

The bsd_signal declaration shouldn't be visible if API > 21.

This causes GNU make to fail to build:

  main.o:main.c:(.text+0x18c): more undefined references to `bsd_signal' follow

Bug: N/A
Test: built GNU make with a hacked standalone toolchain
