Bug 1933890

.`elfutils` rebased to version 0.185 The `elfutils` package has been updated to version 0.185. Notable bug fixes and enhancements include: * The `eu-elflint` and `eu-readelf` tools now recognize and show the `SHF_GNU_RETAIN` and `SHT_X86_64_UNWIND` flags on ELF sections. * The `DEBUGINFOD_SONAME` macro has been added to `debuginfod.h`. This macro can be used with the `dlopen` function to load the `libdebuginfod.so` library dynamically from an application. * A new function `debuginfod_set_verbose_fd` has been added to the `debuginfod-client` library. This function enhances the `debuginfod_find_*` queries functionality by redirecting the verbose output to a separate file. * Setting the `DEBUGINFOD_VERBOSE` environment variable now shows more information about which servers the `debuginfod` client connects to and the HTTP responses of those servers. * The `debuginfod` server provides a new thread-busy metric and more detailed error metrics to make it easier to inspect processes that run on the `debuginfod` server. * The `libdw` library now transparently handles the `DW_FORM_indirect` location value so that the `dwarf_whatform` function returns the actual FORM of an attribute. * To reduce network traffic, the `debuginfod-client` library stores negative results in a cache, and client objects can reuse an existing connection.
