Could not compiler the ppc target with these components.

Steps:

Make a fresh project with Xcode 7.3.1.
2.Set the Base SDK to Mac OS X 10.5
3.Set the Compiler to GCC 4.2
4.Set the Deploy target to OS X 10.5
5.Compiler

Result:

That's an Xcode 7.3 issue. There does not seem to be any way to disable this flag.
You could copy-paste the command-line to a terminal and remove the flags "-Xlinker -no_deduplicate".
Or you could use another build system than Xcode (Makefile, cmake, qmake...).

I fixed the compiler issue. Add a User-Defined build setting
LD_DONT_RUN_DEDUPLICATION and set its value to NO.

Everything goes right.:)

xcodelegacy now installs a ld stub which filters the unsupported arguments, so it should rune fine out of the box. see: https://github.com/devernay/xcodelegacy/blob/master/XcodeLegacy.sh#L746
