[PATCH] cmake/QtBuildInternalsExtra.cmake.in: Patch out embedded build path.
The original build path should not be needed in the shipped package,
and causes reproducibility issues when built in different paths.

use _Float16 only when SSE2 is enabled
Forwarded: https://codereview.qt-project.org/c/qt/qtbase/+/579205
Last-Update: 2024-08-01
The GCC documentation [1] says: “On x86 targets with SSE2 enabled, GCC
supports half-precision (16-bit) floating point via the _Float16 type”.
On non-SSE2 x86 (such as Debian i386 baseline [2]), __FLT16_MAX__ is
defined starting with GCC 14 [3], however any non-trivial use of the
_Float16 type results in an error:
error: operation not permitted on type ‘_Float16’ without option ‘-msse2’
which makes some packages fail to build on i386 architecture [4].

Upstream processes archs from time to time and tends to disable those that
they do not know wether they are working or not.
SH is working on Debian, so as an intermediate measure re enable it here.
