+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_PRE_TLS is defined
+
+csu/libc-tls.c: Use the no-sysenter version of sbrk when
+INTERNAL_SYSCALL_PRE_TLS is defined.
+
+misc/sbrk.c: Define a no-sysenter version of sbrk, using the no-sysenter
+version of brk - if INTERNAL_SYSCALL_PRE_TLS is defined.
+
+misc/brk.c: Define a no-sysenter version of brk if
+INTERNAL_SYSCALL_PRE_TLS is defined.
+
+sysdeps/unix/sysv/linux/i386/sysdep.h: Define INTERNAL_SYSCALL_PRE_TLS
+Make INTERNAL_SYSCALL always use the PIC variant, even if not SHARED.
