fix: ignore '$TMPDIR' when it is an unusable directory#320
Conversation
A recent audit of Ubuntu’s Rust utilities¹ led me to learn that `$TMPDIR` is only intended to be used when the directory it points to is accessible:² If applications are written to use temporary or intermediate files, they should use the _TMPDIR_ environment variable, if it is set and represents an accessible directory, to select the location of temporary files. The effect of this change is that `rumur --help` with an unusable `$TMPDIR` set will now fall back to using /tmp instead of trying (and failing) to use this `$TMPDIR`. ¹ https://discourse.ubuntu.com/t/an-update-on-rust-coreutils/80773 ² https://pubs.opengroup.org/onlinepubs/9799919799/utilities/V3_chap01.html
The Ubuntu toolchain PPA seems to be having an outage wherein (at least) GCC 15 and 16 are not currently available. Bizarrely apt’s behaviour when failing to find an exact package is to treat the package name as a regex, which in the case of g++x matches the corresponding Clang package.¹ This causes a confusing situation where package installation appears to succeed and then compilation either fails to find the expected GCC or incorrectly finds Clang and builds with that. This change should hopefully cause an earlier more obvious failure when GCC fails to install. ¹ https://askubuntu.com/questions/1341002/apt-install-g-10-installs-clang-10-instead-of-g-10
