Keep the target ABI the series already shipped

2026.08.0 ships newlib 6cba9812, vita-headers ebc8f4f7 and
pthread-embedded 610934f4. Master is 2445 newlib commits past that, on
4.6.0, and a patch that swapped the target runtime under people who
already built against this series would not be a patch.

The compiler is not what moves here: gcc 15.2.0, binutils 2.46.1, gdb
15.2 and every host library are identical between the two, and so are
vita-toolchain and the samples. Only the three target components go
back; vdpm and vita-makepkg stay current, since the host side is what
this release exists to fix.
