The s390 indirect thunks are placed in the .text.__s390_indirect_jump_*
sections.
Certain config options which enable -ffunction-sections have a custom
version of the TEXT_TEXT macro:
.text.[0-9a-zA-Z_]*
That unintentionally matches the thunk sections, causing them to get
grouped with normal text rather than being handled by their intended
rule later in the script:
*(.text.*_indirect_*)
Fix that by adding another period to the thunk section names, following
the kernel's general convention for distinguishing code-generated text
sections from compiler-generated ones.
