/* This is not possible in v7 because the label is in another section.

* objdump says that this generates a R_AARCH64_ADR_PRE relocation.
|
|
* which looks specific to ADR, and therefore makes it more likely
|
|
* that there was no such relocation in v7.
|

|
|
* This relocation is particularly important because str does not have a
|
|
* pc-relative mode in ARMv8.
