GCC 15 20250503 dont install its libgccjit.h in the same way as GCC 14

[Basile Starynkevitch]

Hello all,

On Debian/trixie/x86-64 I did compile GCC-15-20240503 (untarred under
/usr/src/Lang) configured as 

'/usr/src/Lang/gcc-15-20250503/configure'   '-v' '--prefix=/usr/local' \
   '--with-gcc-major-version-only' '--program-suffix=-my-15' \
   '--enable-shared' '--enable-plugin' '--enable-default-pie' \
   '--with-system-zlib' '--disable-multilib' '--with-tune=native' \
   '--enable-checking=release' '--enable-host-shared' \ 
   '--enable-languages=c,c++,rust,jit' \
   '--host=x86_64-linux-gnu' \
   '--target=x86_64-linux-gnu' 'CFLAGS=-g -O2' 'CXXFLAGS=-g -O2' \
   '--enable-languages=c,c++,jit,lto,rust'


and to my surprise its libgccjit.h was installed under /usr/local/include/ and
not, as I expected, under /usr/local/lib/gcc/x86_64-linux-gnu/15/include/


I tend to believe that it is a bug or at least should be documented in 
   gcc-15/changes.html

Your opinion is appreciated.

Thanks, regards from France

libgccjit.h has always been installed in $(includedir), so this is
expected.
