On some targets ';' (like hppa) is treated as a comment
in assembly files. This occasionally causes the following
assembly failures:
```
Error: can't resolve `.gnu.warning.EVP_DecryptFinal'
{.gnu.warning.EVP_DecryptFinal section} - `.Ltext0' {.text section}
```
Note how branch (or other reference) attempts to cross the
boundary across two section types: '.text' and '.gnu.warning'.
Tobias Ulmer notes that openbsd already uses newlines
for similar macro:
https://github.com/openbsd/src/blob/master/sys/arch/hppa/include/cdefs.h
This change switches from ';' to newline as well.
Tested on hppa2.0 and x86_64.
