rtld(1): Fix a typo in a source code comment

rtld-elf: on arm, only use -mfpu=none with clang

2021-12-21T14:57:33Z

This is because gcc 4.2.1 in combination with gas 2.17.50 on arm does not support this option. Direct commit to stable/12, since that still has gcc 4.2.1 and gas 2.17.50.

Remove tests for obsolete compilers in the build system

2021-09-02T23:30:12Z

Assume gcc is at least 6.4, the oldest xtoolchain in the ports tree. Assume clang is at least 6, which was in 11.2-RELEASE. Drop conditions for older compilers.

Revert "Do a sweep and remove most WARNS=6 settings"

2021-08-29T13:28:30Z

This reverts commit befc47822966, as it caused various CI build errors, and we never merged the prerequisite commit fe815331bb40 ("build: provide a default WARNS for all in-tree builds"). The latter is rather intrusive, so I will avoid it. Direct commit to stable/12 since the CI bots are broken.

Do a sweep and remove most WARNS=6 settings

2021-08-29T10:49:28Z

Repeating the default WARNS here makes it slightly more difficult to experiment with default WARNS changes, e.g. if we did something absolutely bananas and introduced a WARNS=7 and wanted to try lifting the default to that. Drop most of them; there is one in the blake2 kernel module, but I suspect it should be dropped -- the default WARNS in the rest of the build doesn't currently apply to kernel modules, and I haven't put too much thought into whether it makes sense to make it so.
