glibc: bump SRCREV to latest 2.28

* drop one patch already applied in upstream

* this is still only partial fix for issues with -O0 and the bigger
  issue might be detected in runtime as described in:
  https://sourceware.org/glibc/wiki/FAQ#Why_do_I_get:.60.23error_.22glibc_cannot_be_compiled_without_optimization.22.27.2C_when_trying_to_compile_GNU_libc_with_GNU_CC.3F
  https://sourceware.org/bugzilla/show_bug.cgi?id=19444
  and tested in glibc build:
  https://sourceware.org/git/?p=glibc.git;a=blob;f=include/libc-symbols.h;h=8b9273c13a19f2658105c7997267d9086adae716;hb=HEAD#l74

* restore the anonymous python to trigger fatal error when -O0 is
  used (but don't restore the notes for -O, -O1, -Os

* git log --oneline 3c03baca37fdcb52c3881e653ca392bba7a99c2b..044c96f0d5595aeb0bb4e79355081c5a7f4faca5 | tee
