+Subject: [PATCH] force position independent code
+
+Without this option, programs building for arm64 or x86-64 will fail when
+attempting to link to the built libraries with the following (abbreviated)
+error:
+
+"relocation against `.rodata' can not be used when making a shared object;
+recompile with -fPIC."
+
+Because libabseil-cpp builds static libraries, it is better to set the
+POSITION_INDEPENDENT_CODE to ON instead of forcing fPIC, as forcing fPIC may
+cause relocation errors when shared libraries link against the built static
+libraries.

+Subject: [PATCH] absl/debugging: use <execinfo.h> only when available
+
+Instead of relying on __GLIBC__ or other unreliable detection
+mechanism, simply detect if <execinfo.h> is available before using the
+stacktrace_generic-inl.inc implementation.
