uclibc-git: Update for building systemd
This adds uclibc patches to build systemd there are new functions that are used by systemd which are needed Additionally when using gold linker to build userspace based on uclibc there are spurious hidden symbol that show up in librt.so and libc.so which should not exist So we patch uclibc for that (From OE-Core rev: ecffa7571ed27a75e3248cb860affae233249440) Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

Subject: [PATCH] librt: Use -nodefaultlibs instead of -nostdlib
|
||||
|
||||
nostdlib disables linking in startup files too which is not
|
||||
what we want here since it needs to resolve __dso_handle
|
||||
which comes from crtbeginS.o, otherwise librt has this
|
||||
undefined reference to a weak undefined __dso_handle that
|
||||
shows up as error (with gold linker)
|
||||
when shared libraries are being built which are
|
||||
linking in librt
