Zig Version

0.14.0-dev.2319+1a99c99ee

Steps to Reproduce and Observed Behavior

When linking C with android api level<28, get 'undefined symbol: getrandom'.

Bionic C library supports 'getrandom' until api level 28 (https://android.googlesource.com/platform/bionic/+/HEAD/docs/status.md).

The testing target is

.{
    .cpu_arch = .aarch64,
    .cpu_features_add = aarch64_feature,
    .os_tag = .linux,
    .abi = .android,
    // monkey-patch std.c.getrandom with:
    // .linux => if (if (builtin.abi.isAndroid()) versionCheck(.{ .major = 28, .minor = 0, .patch = 0 }) else versionCheck(.{ .major = 2, .minor = 25, .patch = 0 })) private.getrandom else {},
    .android_api_level = 26,
}

Expected Behavior

getrandom works out of the box.
