Thanks to your and Henrik's advice I am almost done with uplevelling it
to gcc 4.5 from rawhide.
I found that binutils already had almost the same patch, and I just
focused on gcc with glibc.
After some hours of wrestling the set of packages is generated and it
upgrades the 4.1 packages without any conflicts with that or native gcc
install.
I am able to compile an ARM kernel with it OK, which worked perfectly in
a target device, so I thought I was done. But I thought I should check
a hello world c app just as a userspace build sanity check...
$ armv5tel-redhat-linux-gnueabi-gcc hello.c
/usr/bin/armv5tel-redhat-linux-gnueabi-ld: skipping incompatible
/usr/lib/gcc/armv5tel-redhat-linux-gnueabi/4.5.0/libgcc.a when searching
for -lgcc
/usr/bin/armv5tel-redhat-linux-gnueabi-ld: cannot find -lgcc
/usr/bin/armv5tel-redhat-linux-gnueabi-ld: skipping incompatible
/usr/lib/gcc/armv5tel-redhat-linux-gnueabi/4.5.0/libgcc.a when searching

/usr/bin/armv5tel-redhat-linux-gnueabi-ld: cannot find libgcc.a
collect2: ld returned 1 exit status
If I compile with -c, then use armv5tel-redhat-linux-gnueabi-ld directly
on hello.o, I get the same problem.
Looking at the contents of
/usr/lib/gcc/armv5tel-redhat-linux-gnueabi/4.5.0/libgcc.a, I see this:
__gcc_bcmp.o: ELF 32-bit LSB relocatable, ARM, version 1
(SYSV), not stripped
__main.o: ELF 32-bit LSB relocatable, ARM, version 1
(SYSV), not stripped
_absvdi2.o: ELF 32-bit LSB relocatable, ARM, version 1
(SYSV), not stripped
...
_thumb1_case_sqi.o: ELF 32-bit LSB relocatable, no machine,
version 1 (SYSV), not stripped
_thumb1_case_uhi.o: ELF 32-bit LSB relocatable, ARM, version 1

...
unorddf2.o: ELF 32-bit LSB relocatable, ARM, version 1
(SYSV), stripped
unordsf2.o: ELF 32-bit LSB relocatable, ARM, version 1
(SYSV), stripped
They all look reasonable except -->
_thumb1_case_sqi.o: ELF 32-bit LSB relocatable, no machine,
version 1 (SYSV), not stripped
After some Googling, I found a site that recommended disabling strip in
rpmbuild, I did this and confirmed that all the objects then show "not
stripped", but it didn't solve the issue.
I guess the problem is _thumb1_case_sqi.o header but I don't know why...
any ideas?
