so architecture is right but something \"not-good-enough\" for Android in it?
interestingly that `ldd` fiasco since seems to be that the
```
/bin $ nl -ba `which ldd`
1 #!/system/bin/sh
2
3 # Rather than have ldd and ldd64, this script does the right thing depending
4 # on the argument.
5
6 function error() {
7 echo \"$1\"
8 exit 1
9 }
```
and that `system/sh` does not support this syntax! (removal of `function ` seems to not help ..) but that seems to be how many copies of such file distributed [around](https://github.com/search?q=%22rather+than+have+ldd+and+ldd64%22&type=code) . `ldd` starts to work if I remove com.termux's `/bin/` from PATH and start system's `sh`...
But overall that system feels really odd:
```
~ $ ls -ld /
drwxr-xr-x 29 root root 4096 Dec 31 2008 /
~ $ ls -l /
ls: cannot open directory '/': Permission denied
~ $ /wrongpath
bash: /wrongpath: Permission denied
```
so - even through permissions there, `ls` cannot list it with Permissions denied. The same error if just using non-existing path. But it is more appropriate if I am in the system shell, not termux's bash.
