The new swift-driver doesn't seem to work properly when it's used through a symbolic link #70932
Description
Description
SSWG's swiftly installs a Swift toolchain under $SWIFTLY_BIN_DIR (e.g. $HOME/.local/bin).
In fact, they are just symbolic links to executables under $SWIFTLY_HOME_DIR/toolchains/*/usr/bin.

/home/kebo/.local/share/swiftly/toolchains/main-snapshot-2024-01-15/usr/bin/wasm-ldRecently, the main snapshot toolchain began actively using the new swift-driver.
However, the new swift-driver doesn't seem to work properly when it's used through a symbolic link, such as the one swiftly installs.

Reproduction

After following "Steps to reproduce", you can success to build in the following two ways.
- Using the legacy swift-driver
$ swift build -Xswiftc -disallow-use-new-driver Building for debugging... <unknown>:0: warning: legacy driver is now deprecated; consider avoiding specifying '-disallow-use-new-driver' <unknown>:0: warning: legacy driver is now deprecated; consider avoiding specifying '-disallow-use-new-driver' [7/7] Linking example Build complete! (1.76s)- Using executables directly
$ export PATH=$SWIFTLY_HOME_DIR/toolchains/main-snapshot-2024-01-15/usr/bin:$PATH $ swift build Building for debugging... [8/8] Linking example Build complete! (1.69s)Thus, I believe that the combination of the new swift-driver and symbolic links is the cause.
