x86-64: Don't set GLRO(dl_platform) to NULL [BZ #22299]
Since ld.so expands $PLATFORM with GLRO(dl_platform), don't set GLRO(dl_platform) to NULL. [BZ #22299] * sysdeps/x86/cpu-features.c (init_cpu_features): Don't set GLRO(dl_platform) to NULL. * sysdeps/x86_64/Makefile (tests): Add tst-platform-1. (modules-names): Add tst-platformmod-1 and x86_64/tst-platformmod-2. (CFLAGS-tst-platform-1.c): New. (CFLAGS-tst-platformmod-1.c): Likewise. (CFLAGS-tst-platformmod-2.c): Likewise. (LDFLAGS-tst-platformmod-2.so): Likewise. ($(objpfx)tst-platform-1): Likewise. ($(objpfx)tst-platform-1.out): Likewise. (tst-platform-1-ENV): Likewise. ($(objpfx)x86_64/tst-platformmod-2.os): Likewise. * sysdeps/x86_64/tst-platform-1.c: New file. * sysdeps/x86_64/tst-platformmod-1.c: Likewise. * sysdeps/x86_64/tst-platformmod-2.c: Likewise.
