            Bug ID: 22516
           Summary: libc++ buildit script ignores CXX and CC
           Product: libc++
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P

Libc++ ignores CXX and CC if triple == apple.

See the following lines:


CXX=`xcrun -sdk "${SDKROOT}"  -find clang++`
CC=`xcrun -sdk "${SDKROOT}"  -find clang`


One could change them to something like:

if [ -z "$CXX" ]
then
  CXX=`xcrun -sdk "${SDKROOT}"  -find clang++`
fi
if [ -z "$CC" ]
then
  CC=`xcrun -sdk "${SDKROOT}"  -find clang`
fi

but feels like a hack.
