It seems that this version of the GCC does ignore __progmem__ attribute.

Following code (but the same result for other vriable types) produces elf image
with rotor array placed in .data section

const uint8_t rotor[ANIMSTEPS] __attribute__((__progmem__)) = {
        ~(SEG_A)&SEG_MASK, ~(SEG_B)&SEG_MASK, ~(SEG_C)&SEG_MASK,
        ~(SEG_D)&SEG_MASK, ~(SEG_E)&SEG_MASK, ~(SEG_F)&SEG_MASK };

Where SEG_* are simple numeric defines.

Below a fragment of the map file:
.data           0x00800060       0x2c load address 0x00000604
                0x00800060                PROVIDE (__data_start, .)
 *(.data)
 .data          0x00800060       0x2b display.o
                0x00800078                rotor
