Description

Here's what I get 

~/sage$ echo $CC
/projects/66d93023-00f0-4c12-8a25-5d6d4e486740/sage-build/bin/x86_64-conda_cos6-linux-gnu-cc

~/sage$ $CC -print-prog-name=ld
/projects/66d93023-00f0-4c12-8a25-5d6d4e486740/sage-build/bin/../lib/gcc/x86_64-conda_cos6-linux-gnu/7.3.0/../../../../x86_64-conda_cos6-linux-gnu/bin/ld

~/sage$ $CC -print-file-name=ld
ld

~/sage$ echo $LD
/projects/66d93023-00f0-4c12-8a25-5d6d4e486740/sage-build/bin/x86_64-conda_cos6-linux-gnu-ld

Therefore -print-file-name is clearly not what we need. -print-prog-name gives a path with ..s in it.

We need to check that the two files are equivalent using -ef which checks that the files are the same.
