This is a minor bugfix release, which to my knowledge contains nothing of importance to us. However, there is one QoL change to our patches. We no longer force `-fpic` in the compiler driver, and instead use the `--enable-default-pie` configure option to generate position-independent code suitable for executables. For building shared libraries, the `-fpic` flag must be specified explicitly.

Subject: [PATCH] libstdc++: Build static library with -fPIC
|
|
|
|
We want the libstdc++.a library to contain -fPIC code in order to link
|
|
it statically into LibC/our shared objects. However, the build system
|
|
forces no-pic/pie instead.
|
|
|
|
This hack is from https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58638
