Can you help understanding the problem ?
When being in the directory where are the source code of the glibc. Example here below: 2.4 (Same problem with 2.3.4 and 2.3.6 .)
$ ./configure --enable-add-ons=nptl --with-tls --with-__thread .... checking for powerpc64 TLS support... no
configure uses uname -m to make assumptions about what code gcc will generate. But this kind of guessing does not work on ppc and sparc because the gcc defaults to 32bit output. Either use 'powerpc32 ./configure ...' to fool configure and build a 32bit glibc. Or use 'CC='gcc -m64 ./configure ...' to tell gcc to generate 64bit code. You will need some of the -devel-64bit.rpm packages for 64bit libraries.
