   4 Subject: [PATCH] binutils-nativesdk: Search for alternative ld.so.conf in SDK
   5  installation
   6
   7 We need binutils to look at our ld.so.conf file within the SDK to ensure
   8 we search the SDK's libdirs as well as those from the host system.
   9
  10 We therefore pass in the directory to the code using a define, then add
  11 it to a section we relocate in a similar way to the way we relocate the
  12 gcc internal paths. This ensures that ld works correctly in our buildtools
  13 tarball.
  14
  15 Standard sysroot relocation doesn't work since we're not in a sysroot,
  16 we want to use both the host system and SDK libs.
