[PATCH] libgcc: quote ARM macro parameters

[Saleem Abdulrasool]

For ARM EHABI _Unwind_{G,S}setIP are macros rather than proper functions as they
are extensions to the EHABI specification (though they are part of the Level 1
interface).  Quote the macro parameters, as otherwise, a complex parameter may
be ambiguously mis-expanded.
