[gnutls-devel] GnuTLS | wrong text relocations on i386 due to non-PIC assembly (#818)

[Development of GNU's TLS library]

Andreas Metzler commented on a discussion: https://gitlab.com/gnutls/gnutls/issues/818#note_202265159

Afaict simply changing the cfg.mk a la
```
lib/accelerated/x86/elf/%.s: devel/perlasm/%.pl .submodule.stamp 
	CC=gcc perl $< elf {+-fPIC+} $@.tmp
	cat $<.license $@.tmp > $@ && rm -f $@.tmp
```
will not work since not all .s files are buildable when specifying -fPIC to the perl script. The openssl  build.info passes -fPIC selectively:
```
[...]
GENERATE[ghash-x86.s]=asm/ghash-x86.pl \
        $(PERLASM_SCHEME) $(LIB_CFLAGS) $(LIB_CPPFLAGS) $(PROCESSOR)
GENERATE[ghash-x86_64.s]=asm/ghash-x86_64.pl $(PERLASM_SCHEME)
[...]
```
