[macppc] lang/gcc/8: add crt* symbols

Hi,

(I know the timing is unfortunate due to gcc-8 being broken on amd64,
but the proposed changes only impact macppc).

php-7.3 is broken on macppc [0] because it is missing some
_savegpr_/_restgpr_ symbols coming from crt* in libgcc.a.

I'm proposing here a diff that adds additional symbols in libgcc.a,
fixing the php-7.3 build [1]. I've chosen to add them all to avoid
further issues in this regard.

Bumping SHARED_LIBS seems not needed as the additional symbols are not
added to them.

Comments/feedback are welcome,

Charlène.
