Invalid PATH set for `-B` dirs when calling gcc to link
Summary
When -B values are set in -optl, GHC constructs a seemingly invalid PATH from it, using ; instead of : to prepend to the existing PATH.
Steps to reproduce
On a system where all executables needed to run GHC are in /bin:
$ cat Main.hs
module Main where
main = return ()
$ PATH=/bin ghc -optl-B/var/tmp Main
[1 of 1] Compiling Main ( Main.hs, Main.o )
Linking Main ...
collect2: fatal error: cannot find 'ld'
compilation terminated.(strace shows PATH="/var/tmp";/bin being set in the environment).
Expected behavior
Link sample program successfully.
Environment
- GHC version used: 7.6.3 and 8.4.4
Optional:
- Operating System: linux
- System Architecture: x86_64
