359275 - Issues causing bad relocations when building with WRAP_SYSTEM_INCLUDES

Status: RESOLVED INCOMPLETE

(Core Graveyard :: Tracking, defect)

Description

[David Baron :dbaron: (⌚️UTC-4, no longer working on Mozilla)]

This is a meta-bug to track issues that cause bad relocations when configure determines that we can build with WRAP_SYSTEM_INCLUDES, which causes us to set the default visibility to hidden and wrap system includes to mark their contents as having visibility default.  This happens on Linux distros whose gcc has https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=175442 fixed, such as Fedora Core 6.

These bugs generally show up as:
 * linker errors on x86_64
 * runtime problems on i386:
   * failure to run when SELinux is enabled and the library has not
     been marked with "chcon -t textrel_shlib_t"
   * failure to prelink the libraries

Builds with WRAP_SYSTEM_INCLUDES (when it can be enabled and fully works) have fewer relocations that need to be resolved at library load time and fewer function calls that need to go through the PLT (an extra level of indirection).
