Bug#1064629: libamd-comgr2: segfault in rocfft,version graph

[Cordell Bloor <cgmb@slerp.xyz>]

The segfault on the very first rocfft test (and in no other library) is 
probably a good indication that HIP runtime compilation (RTC) is broken. 
That is a feature that is used for every rocFFT function, but not used 
by any other ROCm library.

Whether this bug is because the HIP stack is currently built on a mix of 
clang-15 and clang-17, or if this bug is inherent to the clang-17 
version of comgr is an open question. My priority at the moment is to 
complete the move to clang-17 so we can at least eliminate the clang-15 
variable and re-stabilize the ROCm stack on clang-17.
