Work around a weird code-generation issue [v1.1.3-testing]

Using the 'wcc386' '-ol' flag can result in the generation of different
code, depending on the length of the source-path.

CAUTION:
This is a testbuild !
AirBoot uses the BIOS to access disks and a small coding error can trash
partition tables or other vital disk structures. You are advised to make
backups of TRACK0 and EBRs before using this testbuild. More info at:

117# rousseau.comment.201711092035 :: -ol optimization generates inconsistent code
118# It was already observed that building on Linux could generate different code
119# as when building on OS/2, so releases were always built on OS/2.
120# Lately, however, different code generation was also observed between building
121# on a local drive and on a network drive, both under OS/2. But is was not the
122# local or remote nature of the drive, but it seemed like the length of the
123# path to the sources played a role. Doing two builds on a local drive on OS/2,
124# one with a short path and one with a longer path generated substantially
125# different (prolog / indexing) code at specific locations. The one used a
126# combination of 'mov' and 'add' while the other used 'lea'.
127#
128# This has been tracked down to the wcc386 -ol (enable loop optimizations)
129# flag, which is part of -ox, which is short for -obmiler -s.
130# So the new flags replace -ox with -obmier and since we actually do want
131# stack overflow checking (-s), this flag is not re-added.
132#
133# Now MD5SUMS are the same again, even when building on Linux.
134# This requires further investigation and a cross-check against v1.9+ versions
135# of Open Watcom.

234# DOS WMake has a bug in that it expands $^& and $^. to lowercase,
235# even though the definition is in uppercase.
236# This gives problems when building in an OS/2 DOS-Box on a network
237# share where also a Linux build-environment is active.
238# The Linux build-environment is case sensitive and will not
239# find the lowercase files.
240# For example, a clean from Linux will not work properly in that case.
241# This does not influence building DOS targets on Linux.
242#
243
244#
245# While the DOS build-environment has been kept alive in this version,
246# it has several drawbacks:
247# - No support for long filenames
248# - Very limited memory
249# - JWasmR does not work because of memory limitations
250# - JWasmD does not work at all
251# - Batch scripting is very rudimentairy
252#
253# Therefore, the DOS build-environment will most probably disappear
254# in future versions.
255# This does not influence the building of DOS targets, which can be done
256# on OS/2, Windows or Linux.
