So your system is prohibiting you from running executable files from
/dev/sdb/we/Desktop/. This is why even "sh configure" fails: It lets you
run configure, but you can't run the compiled test programs from that
sort of directory either.

Sorry, I should have said "findmnt /mnt/sdb/", since that is where your
home directory is mounted.
You can check what logical device the relevant directory is located on
by doing:
> df /home/we/Desktop/
Whatever it reports is what we want to check. This is probably /dev/sdb1
or something like that. In that case, "findmnt /dev/sdb1" will likely
give you the same output as "findmnt /mnt/sdb".
You're basically looking for the "noexec" option, as here:
/home/rgheck/ > findmnt /backup
TARGET SOURCE FSTYPE OPTIONS
/backup /dev/sdb1 ext4 rw,noexec,noatime,data=ordered
