be084204 did not add the AArch64 exception: it only made sure the
comments about threads being needed would not be shown on AArch64,
because gdb is never available on AArch64.

The real commit who made gdb unavailable on AArch64 is
0e49733b306b353aad3a29a2c7a6faf25841ef0b. I believe at the time (April
2013), AArch64 was maybe not supported in the mainline gdb.

Therefore, could you check when AArch64 support was added in mainline
gdb ? We currently allow selecting either gdb 7.6 and 7.7 in Buildroot.

Thanks!

Thomas
