RFR: 8031668: (xxs) TOOLCHAIN_FIND_COMPILER unexpectedly resolves symbolic links

[Mike Duigou]

Hello all;

This is a very small change. Currently when TOOLCHAIN_FIND_COMPILER evaluates a compiler it resolves any symbolic links. This behaviour thwarts compiler setups that use a single executable and multiple symbolic links that "curry" configuration information into the link name.
