+Subject: [PATCH 1/2] Use -fPIC on Linux instead of -fpic
+
+On most platforms, these are identical.  However, on a small list of
+platforms, the small -fpic will enforce a limit on GOT size.  However,
+if -fPIC is used instead, then the GOT on these platforms will have no
+limits.  The affected platforms and the respective GOT limits with -fpic
+are:  8k on sparc, 28k on aarch64, and 32k on m68k and powerpc.
+
+See: https://gcc.gnu.org/onlinedocs/gcc/Code-Gen-Options.html#index-fpic
