cmd/link: fix sym sect when splitting text on ppc64le
While processing a symbol for a function, if it is determined
that a function would make the text section too large then
a new text section is created and the address of the function
is in the new text section. But the symbol for the function
is marked as being in the previous text section, causing
incorrect codegen for the function and leading to a segv if
that function is called. This adds code to set the sym.Sect
field to the new section if a new one is created. Note that
this problem only happens at the point where a new section is
created.
Fixes #18218
