[DTrace-devel] [PATCH 1/2] tests: do not pass -flto to the compiler or linker

[Nick Alcock]

We don't want to compile tests with -flto by default: if the distro
compiler automatically activates it, turn it off by explicitly passing
-fno-lto to all compiler and linker invocations in the testsuite.

(This is a bit fiddly because this is the first CPPFLAG which is
not also a valid flag to dtrace(1) itself, so we have to split
a variable up a bit.)
