Patches for mold on Minerva

0001-Tell-TBB-that-Minerva-does-not-support-weak-symbo.patch

Tell TBB that Minerva does not support weak symbols

Something about the Clang toolchain configuration causes undefined weak references to scalable_malloc to remain in the mold executable even though there's no chance we'll be loading the tbbmalloc library at runtime. So, just lie to TBB that we don't support weak symbols.

0002-Tell-TBB-that-Minerva-libraries-are-named-like-BS.patch

Tell TBB that Minerva libraries are named like BSD ones

We won't be loading these libraries when building TBB as a static library for mold, but the OS detection logic still needs updated.

0003-Stub-out-a-definition-of-RTLD_NOLOAD.patch

Stub out a definition of RTLD_NOLOAD

Minerva's DynamicLoader doesn't support this flag. However, we won't be dynamically loading any tbb extensions for the static library build mold uses, so we can just define it as a no-op as the code paths that use it will never be used.

0004-Disable-mold-wrapper.so-on-Minerva.patch

Disable mold-wrapper.so on Minerva

0005-Replace-lockf-fd-F_LOCK-0-with-flock-fd-LOCK_EX.patch

Replace lockf(fd, F_LOCK, 0) with flock(fd, LOCK_EX)

We don't have the former implemented.
