Remove unneeded enabled flags in host gcc #130

Closed firasuke closed 4 years ago

firasuke commented 4 years ago

Removed unnecessary flags:

--enable-__cxa_atexit is only needed for glibc:

From https://gcc.gnu.org/install/configure.html:

Define if you want to use __cxa_atexit, rather than atexit, to register C++ destructors for local statics and global objects. This is essential for fully standards-compliant handling of destructors, but requires __cxa_atexit in libc. This option is currently only available on systems with GNU libc. When enabled, this will cause -fuse-cxa-atexit to be passed by default.

--enable-checking=release is enabled by default when GCC is being built from a release tarball (check https://gcc.gnu.org/install/configure.html)
--enable-shared is enabled by default
--enable-lto is enabled by default (check GCC configure script)
--enable-plugins is enabled by default (check GCC configure script)
