Subject: Ada bootstrap failure on mainline

Bootstrapping GNAT failes with the following error (on Debian/x86):

a-ngcoty.adb: In function `ada.numerics.short_complex_types."abs"':
a-ngcoty.adb:395: unrecognizable insn:
(insn 21 17 24 (set (reg/i:SF 8 st(0))
        (abs:SF (reg/v/u:SF 59))) -1 (insn_list 4 (nil))
    (expr_list:REG_UNUSED (reg:CC 17 flags)
        (expr_list:REG_DEAD (reg/v/u:SF 59)
            (nil))))
