-When building glibc PIE (which is not something upstream support),
-several modifications are necessary to the glibc build process.
-
-First, any syscalls in PIEs must be of the PIC variant, otherwise
-textrels ensue.  Then, any syscalls made before the initialisation
-of the TLS will fail on i386, as the sysenter variant on i386 uses
-the TLS, giving rise to a chicken-and-egg situation.  This patch
-defines a PIC syscall variant that doesn't use sysenter, even when the sysenter
-version is normally used, and uses the non-sysenter version for the brk
-syscall that is performed by the TLS initialisation.  Further, the TLS
-initialisation is moved in this case prior to the initialisation of
-dl_osversion, as that requires further syscalls.
-
-csu/libc-start.c: Move initial TLS initialization to before the
-initialisation of dl_osversion, when INTERNAL_SYSCALL_NOSYSENTER is defined
-
-csu/libc-tls.c: Use the no-sysenter version of sbrk when
-INTERNAL_SYSCALL_NOSYSENTER is defined.
-
-misc/sbrk.c: Define a no-sysenter version of sbrk, using the no-sysenter
-version of brk - if INTERNAL_SYSCALL_NOSYSENTER is defined.
-
-misc/brk.c: Define a no-sysenter version of brk if
-INTERNAL_SYSCALL_NOSYSENTER is defined.
-
-sysdeps/unix/sysv/linux/i386/sysdep.h: Define INTERNAL_SYSCALL_NOSYSENTER
-Make INTERNAL_SYSCALL always use the PIC variant, even if not SHARED.
