[fpc-devel] Current Trunk does not build for target embedded amd ARM-Cortex-M0 (Introduced in Rev 25370)

[Michael Ring]

Trunk for armv7m buils just fine with this commandline:

make clean buildbase CROSSINSTALL=1 OS_TARGET=embedded CPU_TARGET=arm 
SUBARCH=armv7m CROSSOPT="-O-" BINUTILSPREFIX=arm-none-eabi-

doing the same for armv6m:

make clean buildbase CROSSINSTALL=1 OS_TARGET=embedded CPU_TARGET=arm 
SUBARCH=armv6m CROSSOPT="-O-" BINUTILSPREFIX=arm-none-eabi-

gives the following errormessage:

make -C embedded all

The problem started with rev 25370, all version before that build fine 
on armv6m

Comments for 25370 were:

+ arm: tsettings.instructionset
* the selected instruction set is now independent from the cpu type: e.g. armv7-a can perfectly execute thumb(2) code
