-From: Christian Prochaska <christian.prochaska@genode-labs.com>
-
-Remove sanity check for host/target combination in configure script of
-libstdc++. An alternative fix would be the addition of a new host or
-the use of an existing one. However, adding a new host would require
-us to maintain a larger patch to the GCC build system, and using an
-existing host comes with all the (possibly unwanted) policies associated
-with the respective host platform. We want to stick with the bare-bone
-compiler as much as possible.

+From: Christian Prochaska <christian.prochaska@genode-labs.com>
+
+Remove sanity check for host/target combination in configure script of
+libstdc++. An alternative fix would be the addition of a new host or
+the use of an existing one. However, adding a new host would require
+us to maintain a larger patch to the GCC build system, and using an
+existing host comes with all the (possibly unwanted) policies associated
+with the respective host platform. We want to stick with the bare-bone
+compiler as much as possible.

+Without this change, libsupc++ would be compiled w/o PIC flags, resulting
+in text relocations. Because for base tool chains, no 'dynamic_linker'
+is defined (see 'libtool.m4'), 'dynamic_linker' is set to 'no', which
+results in 'can_build_shared = no', which, in turn , results
+in 'enable_shared = no', which, in turn, sets 'glibcxx_lt_pic_flag' to
+nothing rather than '-prefer-pic'.
