Prefer https to http for gnu.org and fsf.org URLs
Also, change sources.redhat.com to sourceware.org.
This patch was automatically generated by running the following shell
script, which uses GNU sed, and which avoids modifying files imported
from upstream:
sed -ri '
s,(http|ftp)(://(.*\.)?(gnu|fsf|sourceware)\.org($|[^.]|\.[^a-z])),https\2,g
s,(http|ftp)(://(.*\.)?)sources\.redhat\.com($|[^.]|\.[^a-z]),https\2sourceware.org\4,g

and then by running 'make dist-prepare' to regenerate files built
from the altered files, and then executing the following to cleanup:
chmod a+x sysdeps/unix/sysv/linux/riscv/configure
# Omit irrelevant whitespace and comment-only changes,
# perhaps from a slightly-different Autoconf version.
git checkout -f \

S390: Use s390-64 specific ionv-modules on s390-32, too.
This patch reworks the existing s390 64bit specific iconv modules in order
to use them on s390 31bit, too.
Thus the parts for subdirectory iconvdata in sysdeps/s390/s390-64/Makefile
were moved to sysdeps/s390/Makefile so that they apply on 31bit, too.
All those modules are moved from sysdeps/s390/s390-64 directory to sysdeps/s390.
The iso-8859-1 to/from cp037 module was adjusted, to use brct (branch relative
on count) instruction on 31bit s390 instead of brctg, because the brctg is a
zarch instruction and is not available on a 31bit kernel.
The utf modules are using zarch instructions, thus the directive machinemode
zarch_nohighgprs was added to the inline assemblies to omit the high-gprs flag
in the shared libraries. Otherwise they can't be loaded on a 31bit kernel.
The ifunc resolvers were adjusted in order to call the etf3eh or vector variants
only if zarch instructions are available (64bit kernel in 31bit compat-mode).
Furthermore some variable types were changed. E.g. unsigned long long would be
a register pair on s390 31bit, but we want only one single register.
For variables of type size_t the register contents have to be enlarged from a
32bit to a 64bit value on 31bit, because the inline assemblies uses 64bit values
in such cases.
ChangeLog:
* sysdeps/s390/s390-64/Makefile (iconvdata-subdirectory):
Move to ...
* sysdeps/s390/Makefile: ... here.
