-Subject: [PATCH] ext-toolchain-wrapper: fix paths if executable was resolved
- by PATH
-
-If ext-toolchain-wrapper or any symbolic link to it was resolved by PATH,
-the wrapper takes the working directory to calculate the relative paths.
-
-Now '/proc/self/exe' is used to resolve the absolute path to the toolchain
-directory if the wrapper was called neither with a relative nor an absolute
-path.
