linux-arm's frida-server doesn't work when attaching to a process

[wenkane]

I build a linux-arm version frida-server for myself, and the version is 14.2.18.62.g92c1e68. But when I try to attach to a process, the frida-server stuck at the 'pool-frida' thread and nothing continue. And a few seconds(like 10s) later, the thread exited. But still nothing happens both in frida-server and frida tools.

here's the info:
(gdb) c

// then nothing happens both the frida-server and the frida-tools . and the frida-tool shows I am still ataching to the process.
