--- Comment #1 from Rainer Orth <ro at gcc dot gnu.org> ---
I just had the same problem again (this time with gas/gld 2.30) on Solaris
11.4/x86:

I tried to build gcc mainline with --enable-host-shared --enable-languages=jit,
but running cc1 fails:

/var/gcc/regression/trunk/11.4-gcc-gas-gld/build/./gcc/xgcc
-B/var/gcc/regression/trunk/11.4-gcc-gas-gld/build/./gcc/ -xc -nostdinc
/dev/null -S -o /dev/null
-fself-test=/vol/gcc/src/hg/trunk/solaris/gcc/testsuite/selftests
ld.so.1: cc1: fatal: relocation error: R_386_UNKNOWN37: file
/var/gcc/regression/trunk/11.4-gcc-gas-gld/build/gcc/cc1: symbol __gmpfr_emin:
offset size (0 bytes) is not supported
xgcc: fatal error: Killed signal terminated program cc1
compilation terminated.
make[3]: *** [Makefile:1972: s-selftest-c] Error 1

R_386_UNKNOWN37 above is R_386_TLS_TPOFF32, and the current (Solaris 11.4)
<sys/elf_i386.h> has

#define R_386_UNKNOWN24         24
#define R_386_UNKNOWN25         25
#define R_386_UNKNOWN26         26
#define R_386_UNKNOWN27         27
#define R_386_UNKNOWN28         28
#define R_386_UNKNOWN29         29
#define R_386_UNKNOWN30         30
#define R_386_UNKNOWN31         31

#define R_386_UNKNOWN37         37      /* reserved for future expansion */
#define R_386_SIZE32            38      /* reserved for future expansion */
#define R_386_TLS_GOTDESC       39      /* reserved for future expansion */
#define R_386_TLS_DESC_CALL     40      /* reserved for future expansion */
#define R_386_TLS_DESC          41      /* reserved for future expansion */
#define R_386_IRELATIVE         42      /* GNU/Linux specific (STT_GNU_IFUNC)
*/
