Comment (by kencu):
coincidence.
By default the system will use a certain assembler. This was causing lots
of build failures for newer software using newer assembly, so that was
changed a few years ago to use the most current clang available.
This has been 99% a good thing, but rarely certain software does not
expect it, esp building gcc. But it's so complicated to figure out exactly
what is wrong that only a few people have the insight into the issue
sufficiently to know.
Last one we fixed, gcc was configuring itself with a certain expectation
of the assembler capabilities based on the new assembly being tested for
an found, but the rest of the toolchain could not support the newer
features.
